TPS61030,TPS61031,TPS61032 www.ti.com SLUS534G–SEPTEMBER2002–REVISEDMARCH2015 10 Detailed Description 10.1 Overview The TPS6103x synchronous step-up converter typically operates at a 600 kHz frequency pulse width modulation (PWM) at moderate to heavy load currents. The converter enters Power Save mode at low load currents to maintain a high efficiency over a wide load. The Power Save mode can also be disabled, forcing the converter to operate at a fixed switching frequency. The TPS6103x family is based on a fixed frequency with multiple feed forward controller topology. Input voltage, output voltage, and voltage drop on the NMOS switch are monitored and forwarded to the regulator. The peak current of the NMOS switch is also sensed to limit the maximum current flowing through the switch and the inductor. It can also operate synchronized to an external clock signal that is applied to the SYNC pin. Additionally, TPS6103x integrated the low-battery detector circuit typically used to supervise the battery voltage and to generate an error flag when the battery voltage drops below a user-set thresholdvoltage. 10.2 Functional Block Diagram SW VOUT Anti- VBAT Ringing PGND PGND Gate Control PGND 100 k(cid:1) 10 pF Error Amplifier _ FB Regulator + + VREF = 0.5 V _ Control Logic Oscillator GND Temperature EN Control SYNC GND LBI + Low Battery Comparator _ LBO + _ VREF = 0.5 V GND Copyright©2002–2015,TexasInstrumentsIncorporated SubmitDocumentationFeedback 9 ProductFolderLinks:TPS61030 TPS61031 TPS61032

TPS61030,TPS61031,TPS61032 SLUS534G–SEPTEMBER2002–REVISEDMARCH2015 www.ti.com 10.3 Feature Description 10.3.1 ControllerCircuit The controller circuit of the device is based on a fixed frequency multiple feedforward controller topology. Input voltage, output voltage, and voltage drop on the NMOS switch are monitored and forwarded to the regulator. So changes in the operating conditions of the converter directly affect the duty cycle and must not take the indirect andslowwaythroughthecontrolloopandtheerroramplifier.Thecontrolloop,determinedbytheerroramplifier, only has to handle small signal errors. The input for it is the feedback voltage on the FB pin or, at fixed output voltage versions, the voltage on the internal resistor divider. It is compared with the internal reference voltage to generateanaccurateandstableoutputvoltage. ThepeakcurrentoftheNMOSswitchisalsosensedtolimitthemaximumcurrentflowingthroughtheswitchand the inductor. The typical peak current limit is set to 4000 mA. An internal temperature sensor prevents the device fromgettingoverheatedincaseofexcessivepowerdissipation. 10.3.2 SynchronousRectifier The device integrates an N-channel and a P-channel MOSFET transistor to realize a synchronous rectifier. Because the commonly used discrete Schottky rectifier is replaced with a low RDS(ON) PMOS switch, the power conversion efficiency reaches 96%. To avoid ground shift due to the high currents in the NMOS switch, two separate ground pins are used. The reference for all control functions is the GND pin. The source of the NMOS switch is connected to PGND. Both grounds must be connected on the PCB at only one point close to the GND pin. A special circuit is applied to disconnect the load from the input during shutdown of the converter. In conventional synchronous rectifier circuits, the backgate diode of the high-side PMOS is forward biased in shutdown and allows current flowing from the battery to the output. This device however uses a special circuit which takes the cathode of the backgate diode of the high-side PMOS and disconnects it from the source when theregulatorisnotenabled(EN=low). The benefit of this feature for the system design engineer is that the battery is not depleted during shutdown of the converter. No additional components have to be added to the design to make sure that the battery is disconnectedfromtheoutputoftheconverter. 10.4 Device Functional Modes 10.4.1 DeviceEnable The device is put into operation when EN is set high. It is put into a shutdown mode when EN is set to GND. In shutdown mode, the regulator stops switching, all internal control circuitry including the low-battery comparator is switched off, and the load is isolated from the input (as described in the Synchronous Rectifier Section). This also means that the output voltage can drop below the input voltage during shutdown. During start-up of the converter, the duty cycle and the peak current are limited in order to avoid high peak currents drawn from the battery. 10.4.1.1 UndervoltageLockout An undervoltage lockout function prevents device start-up if the supply voltage on VBAT is lower than approximately 1.6 V. When in operation and the battery is being discharged, the device automatically enters the shutdown mode if the voltage on VBAT drops below approximately 1.6 V. This undervoltage lockout function is implementedinordertopreventthemalfunctioningoftheconverter. 10.4.2 Softstart When the device enables the internal start-up cycle starts with the first step, the precharge phase. During precharge, the rectifying switch is turned on until the output capacitor is charged to a value close to the input voltage.Therectifyingswitchcurrentislimitedinthatphase.Thisalsolimitstheoutputcurrentundershort-circuit conditions at the output. After charging the output capacitor to the input voltage the device starts switching. Until the output voltage is reached, the boost switch current limit is set to 40% of its nominal value to avoid high peak currents at the battery during startup. When the output voltage is reached, the regulator takes control and the switchcurrentlimitissetbackto100%. 10 SubmitDocumentationFeedback Copyright©2002–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS61030 TPS61031 TPS61032

To enable power save, SYNC must be set low. Power save mode is used to improve efficiency at light load. In power save mode the converter only operates when the output voltage trips below a set threshold voltage. It ramps up the output voltage with one or several pulses and goes again into power save mode once the output voltage exceeds the set threshold voltage. This powersavemodecanbedisabledbysettingtheSYNCtoVBAT. Applying an external clock with a duty cycle between 30% and 70% at the SYNC pin forces the converter to operate at the applied clock frequency. The external frequency has to be in the range of about ±20% of the nominalinternalfrequency.Detailedvaluesareshownintheelectricalcharacteristicsectionofthedatasheet. 10.4.4 LowBatteryDetectorCircuit—LBI/LBO The low-battery detector circuit is typically used to supervise the battery voltage and to generate an error flag when the battery voltage drops below a user-set threshold voltage. The function is active only when the device is enabled. When the device is disabled, the LBO pin is high-impedance. The switching threshold is 500 mV at LBI. During normal operation, LBO stays at high impedance when the voltage, applied at LBI, is above the threshold. ItisactivelowwhenthevoltageatLBIgoesbelow500mV. The battery voltage, at which the detection circuit switches, can be programmed with a resistive divider connected to the LBI pin. The resistive divider scales down the battery voltage to a voltage level of 500 mV, which is then compared to the LBI threshold voltage. The LBI pin has a built-in hysteresis of 10 mV. See the application section for more details about the programming of the LBI threshold. If the low-battery detection circuit is not used, the LBI pin should be connected to GND (or to VBAT) and the LBO pin can be left unconnected.DonotlettheLBIpinfloat. 10.4.5 Low-EMISwitch The device integrates a circuit that removes the ringing that typically appears on the SW node when the converterentersdiscontinuouscurrentmode.Inthiscase,thecurrentthroughtheinductorrampstozeroandthe rectifying PMOS switch is turned off to prevent a reverse current flowing from the output capacitors back to the battery. Due to the remaining energy that is stored in parasitic components of the semiconductor and the inductor, a ringing on the SW pin is induced. The integrated antiringing switch clamps this voltage to VBAT and thereforedampensringing.

The typical value of the voltage on the FB pin is 500 mV. The maximum allowed value for the output voltage is 5.5 V. The current through the resistive divider should be about 100 times greater than the current into the FB pin.ThetypicalcurrentintotheFBpinis0.01 µA,andthevoltageacrossR6istypically500mV.Basedonthose two values, the recommended value for R4 should be lower than 500 kΩ, in order to set the divider current at 1 µA or higher. Because of internal compensation circuitry the value for this resistor should be in the range of 200 kΩ. From that, the value of resistor R3, depending on the needed output voltage (V ), can be calculated using O equation1: (cid:4)V (cid:5) (cid:4) V (cid:5) R3(cid:3)R4(cid:1) O (cid:2)1 (cid:3)180k(cid:1)(cid:1) O (cid:2)1 V 500mV FB (1) If as an example, an output voltage of 3.3 V is needed, a 1-MΩ resistor should be chosen for R3. If for any reason the value for R4 is chosen significantly lower than 200 kΩ additional capacitance in parallel to R3 is recommended.TherequiredcapacitancevaluecanbeeasilycalculatedusingEquation2: (cid:3)200k(cid:1) (cid:4) CparR3(cid:2)10pF(cid:1) R4 –1 (2) 11.2.2.2 ProgrammingTheLBI/LBOThresholdVoltage The current through the resistive divider should be about 100 times greater than the current into the LBI pin. The typical current into the LBI pin is 0.01 µA, and the voltage across R2 is equal to the LBI voltage threshold that is generatedon-chip,whichhasavalueof500mV.TherecommendedvalueforR2 isthereforeintherangeof500 kΩ.

The output requires a pullup resistor with a recommended value of 1 MΩ. The maximum voltage which is used to pull up the LBO outputs should not exceedtheoutputvoltageofthedc/dcconverter.Ifnotused,theLBOpincanbeleftfloatingortiedtoGND. 11.2.2.3 InductorSelection A boost converter normally requires two main passive components for storing energy during the conversion. A boost inductor and a storage capacitor at the output are required. To select the boost inductor, it is recommended to keep the possible peak inductor current below the current limit threshold of the power switch in the chosen configuration. For example, the current limit threshold of the TPS6103x's switch is 4500 mA at an output voltage of 5 V. The highest peak current through the inductor and the switch depends on the output load, theinput(V ),andtheoutputvoltage(V ).Estimationofthemaximumaverageinductorcurrentcanbedone BAT OUT usingEquation4: V I (cid:2)I (cid:1) OUT L OUT V (cid:1)0.8 BAT (4) For example, for an output current of 1000 mA at 5 V, at least 3500 mA of average current flows through the inductorataminimuminputvoltageof1.8V. The second parameter for choosing the inductor is the desired current ripple in the inductor. Normally, it is advisable to work with a ripple of less than 20% of the average inductor current. A smaller ripple reduces the magnetic hysteresis losses in the inductor, as well as output voltage ripple and EMI. But in the same way, regulation time at load changes rises. In addition, a larger inductor increases the total system costs.

With the calculated inductance and current values, it is possible to choose a suitable inductor.

A ceramic capacitor or a tantalum capacitor with a 100-nF ceramic capacitor in parallel,placedclosetotheIC,isrecommended. 11.2.2.4.2 OutputCapacitor The major parameter necessary to define the output capacitor is the maximum allowed output voltage ripple of the converter. This ripple is determined by two parameters of the capacitor, the capacitance and the ESR. It is possible to calculate the minimum capacitance needed for the defined ripple, supposing that the ESR is zero, by usingEquation6: IOUT(cid:1)(cid:4)VOUT(cid:2)VBAT(cid:5) Cmin(cid:3) ƒ(cid:1)(cid:1)V(cid:1)VOUT (6) ParameterfistheswitchingfrequencyandΔVisthemaximumallowedripple. With a chosen ripple voltage of 10 mV, a minimum capacitance of 100 µF is needed. The total ripple is larger due to the ESR of the output capacitor. This additional component of the ripple can be calculated using Equation7: (cid:1)V (cid:2)I (cid:1)R ESR OUT ESR (7) Anadditionalrippleof80mVistheresultofusingatantalumcapacitorwithalowESRof80mΩ.Thetotalripple is the sum of the ripple caused by the capacitance and the ripple caused by the ESR of the capacitor. In this example, the total ripple is 90 mV. Additional ripple is caused by load transients. This means that the output capacitanceneedstobelargerthancalculatedabovetomeetthetotalripplerequirements. The output capacitor must completely supply the load during the charging phase of the inductor. A reasonable value of the output capacitance depends on the speed of the load transients and the load current during the load change. With the calculated minimum value of 100 µF and load transient considerations, a recommended output capacitance value is in around 220 µF. For economical reasons this usually is a tantalum capacitor. Because of this the control loop has been optimized for using output capacitors with an ESR of above 30 mΩ. The minimum valuefortheoutputcapacitoris22µF. 14 SubmitDocumentationFeedback Copyright©2002–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS61030 TPS61031 TPS61032

If the layout is not carefully done, the regulator could show stability problems as well as EMI problems. Therefore, use wide and short traces for the main current path and for the power ground tracks. The input capacitor, output capacitor, and the inductor should be placed as close as possible to the IC. Use a common ground node for power ground and a different one for control ground to minimize the effects of groundnoise.ConnectthesegroundnodesatanyplaceclosetooneofthegroundpinsoftheIC. The feedback divider should be placed as close as possible to the control ground pin of the IC. To lay out the control ground, it is recommended to use short traces as well, separated from the power ground traces. This avoids ground shift problems, which can occur due to superimposition of power ground current and control groundcurrent. 13.2 Layout Example VIA to Ground Plane Input Capacitor VIA to VBAT Plane T D D D A N N N Inductor B G G G LBI V P P P Resistor 1 LBI SW SYNC SW Output LBI Exposed PAD Capacitor 2 Resistor 2 EN NC LBO VOUT GND G F V V N B O O D U U Feedback T T Feedback Resistor 2 Output Resistor 1 LBO Resistor Capacitor 1 GND 13.3 Thermal Considerations Implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires special attention to power dissipation.
