TPS62065,TPS62067 www.ti.com SLVS833D–MARCH2010–REVISEDNOVEMBER2016 8 Detailed Description 8.1 Overview The TPS6206x step down converter operates with typically 3-MHz fixed frequency pulse width modulation (PWM) at moderate to heavy load currents. At light load currents the converter can automatically enter power savemodeandoperatestheninpulsefrequencymodulation(PFM)mode. During PWM operation the converter use a unique fast response voltage mode controller scheme with input voltage feed-forward to achieve good line and load regulation allowing the use of small ceramic input and output capacitors. At the beginning of each clock cycle initiated by the clock signal, the high-side MOSFET switch is turned on. The current flows now from the input capacitor through the high-side MOSFET switch through the inductortotheoutputcapacitorandload.Duringthisphase,thecurrentrampsupuntilthePWMcomparatortrips and the control logic will turn off the switch. The current limit comparator will also turn off the switch in case the current limit of the high-side MOSFET switch is exceeded. After a dead time preventing shoot through current, the low-side MOSFET rectifier is turned on and the inductor current ramps down. The current flows now from the inductor to the output capacitor and to the load. It returns back to the inductor through the low-side MOSFET rectifier.. The next cycle will be initiated by the clock signal again turning off the low-side MOSFET rectifier and turning on thehigh-sideMOSFETswitch. 8.2 Functional Block Diagram AVIN PVIN Current Limit Comparator Thermal Undervoltage Shutdown Lockout 1.8V Limit High Side PFM Comparator Reference 0.6V VREF FB VREF Softstart VOUTRAMP ErrorAmp.

Connecting this pin to GND enables the power save mode with automatic transition between PWM and PFM mode. Pulling the MODE pin high forces the converter to operate in fixed frequency PWM mode even at light loadcurrents.Thisallowssimplefilteringoftheswitchingfrequencyfornoisesensitiveapplications.Inthismode, theefficiencyislowercomparedtothepowersavemodeduringlightloads. The condition of the MODE pin can be changed during operation and allows efficient power management by adjustingtheoperationmodeoftheconvertertothespecificsystemrequirements. In device options where the MODE pin is replaced with power good output, the power save mode is enabled per default. 8.3.2 PowerGoodOutput(TPS62067) This function is available in the TPS62067. The power good output is an open-drain output and requires an external pullup resistor. The circuit is active once the device is enabled and AVIN is above the undervoltage lockout threshold V . It is driven by an internal comparator connected to the FB voltage. The PG output UVLO provides a high level once the feedback voltage exceeds typically 95% of its nominal value. The PG output is driven to low level once the feedback voltage falls below typically 90% of its nominal value. The PG output is activatedwithaninternaldelayof5 µs. The PG open-drain output transistor is turned on immediately with EN = Low level and pulls the output low. The external pullup resistor can be connected to any voltage rail lower or equal the voltage applied to AVIN of the device.ThevalueofthepullupresistormustbecarefullyselectedtolimitthecurrentintothePGpintomaximum 1 mA. The external pullup resistor can be connected to VOUT or another voltage rail which does not exceed the V level. The current flowing through the pullup resistor impacts the current consumption of the application IN circuitinshutdownmode. The shutdown current of the device does not include the current through the external pullup and internal open- drainstage.ThePGsignalcanbeusedforsequencingvariousconvertersortoresetamicrocontroller. EN Startup Overload VOUT 95% Output 90% discharge tRamp tStart PG WithEN = low PG --> low Figure7. PowerGoodOutputPg 8.3.3 Enable The device is enabled by setting EN pin to high. At first, the internal reference is activated and the internal analog circuits are settled. Afterwards, the soft start is activated and the output voltage is ramped up. The output voltages reaches 95% of its nominal value within t of typically 500 µs after the device has been enabled. START The EN input can be used to control power sequencing in a system with various DC/DC converters. The EN pin can be connected to the output of another converter, to drive the EN pin high and getting a sequencing of supply rails. With EN = GND, the device enters shutdown mode. In this mode, all circuits are disabled and the SW pin is connectedtoPGNDthroughaninternalresistortodischargetheoutput. 8 SubmitDocumentationFeedback Copyright©2010–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS62065 TPS62067

TPS62065,TPS62067 www.ti.com SLVS833D–MARCH2010–REVISEDNOVEMBER2016 Feature Description (continued) 8.3.4 ClockDithering To reduce the noise level of switch frequency harmonics in the higher RF bands, the TPS6206x family has a built-in clock-dithering circuit. The oscillator frequency is slightly modulated with a sub clock causing a clock ditheroftypically6ns. 8.3.5 UndervoltageLockout The undervoltage lockout circuit prevents the device from malfunctioning at low input voltages and from excessive discharge of the battery. It disables the output stage of the converter once the falling V trips the IN undervoltage lockout threshold V . The undervoltage lockout threshold V for falling V is typically 1.78 V. UVLO UVLO IN The device starts operation once the rising V trips undervoltage lockout threshold V again at typically 1.95 IN UVLO V. 8.3.6 ThermalShutdown As soon as the junction temperature, T , exceeds 150°C (typical) the device goes into thermal shutdown. In this J mode, the high-side and low-side MOSFETs are turned off. The device continues its operation with a soft start oncethejunctiontemperaturefallsbelowthethermalshutdownhysteresis. 8.4 Device Functional Modes 8.4.1 SoftStart The TPS6206x has an internal soft start circuit that controls the ramp up of the output voltage. Once the converter is enabled and the input voltage is above the undervoltage lockout threshold V the output voltage UVLO rampsupfrom5%to95%ofitsnominalvaluewithint oftypically250µs. Ramp This limits the inrush current in the converter during start-up and prevents possible input voltage drops when a batteryorhighimpedancepowersourceisused. During soft start, the switch current limit is reduced to 1/3 of its nominal value I until the output voltage LIMF reaches 1/3 of its nominal value. Once the output voltage trips this threshold, the device operates with its nominalcurrentlimitI . LIMF 8.4.2 PowerSaveMode At TPS62065 pulling the MODE pin low enables power save mode. In TPS62067 power save mode is enabled per default. If the load current decreases, the converter enters power save mode operation automatically. During power save mode the converter skips switching and operates with reduced frequency in PFM mode with a minimum quiescent current to maintain high efficiency. The converter positions the output voltage typically +1% above the nominal output voltage. This voltage positioning feature minimizes voltage drops caused by a sudden loadstep. The transition from PWM mode to PFM mode occurs once the inductor current in the low-side MOSFET switch becomeszero,whichindicatesdiscontinuousconductionmode. During the power save mode the output voltage is monitored with a PFM comparator. As the output voltage falls belowthePFMcomparatorthresholdofV +1%,thedevicestartsaPFMcurrentpulse.Forthisthehigh- OUTnominal side MOSFET switch will turn on and the inductor current ramps up. After the on-time expires the switch will be turnedoffandthelow-sideMOSFETswitchwillbeturnedonuntiltheinductorcurrentbecomeszero. The converter effectively delivers a current to the output capacitor and the load. If the load is below the delivered current the output voltage will rise. If the output voltage is equal or higher than the PFM comparator threshold, thedevicestopsswitchingandentersasleepmodewithtypically18 µAcurrentconsumption. In case the output voltage is still below the PFM comparator threshold, further PFM current pulses will be generated until the PFM comparator threshold is reached. The converter starts switching again once the output voltagedropsbelowthePFMcomparatorthresholdduetotheloadcurrent. The PFM mode is exited and PWM mode entered in case the output current can no longer be supported in PFM mode.

In this case the converter IN offers a low input-to-output voltage difference. This is particularly useful in battery-powered applications to achievelongestoperationtimebytakingfulladvantageofthewholebatteryvoltagerange. The minimum input voltage to maintain regulation depends on the load current and output voltage, and can be calculatedas: V min=V max+I max×(R max+R ) IN O O DS(on) L where • I max=maximumoutputcurrent O • R max=maximumP-channelswitchR DS(on) DS(on) • R =DCresistanceoftheinductor L • V max=nominaloutputvoltageplusmaximumoutputvoltagetolerance (1) O 8.4.5 InternalCurrentLimitandFold-BackCurrentLimitforShortCircuitProtection During normal operation the high-side and low-side MOSFET switches are protected by its current limits I . LIMF Once the high-side MOSFET switch reaches its current limit, it is turned off and the low-side MOSFET switch is turned on. The high-side MOSFET switch can only turn on again, once the current in the low-side MOSFET switch decreases below its current limit I . The device is capable to provide peak inductor currents up to its LIMF internalcurrentlimit . ILIMF. As soon as the switch current limits are hit and the output voltage falls below 1/3 of the nominal output voltage due to overload or short circuit condition, the foldback current limit is enabled. In this case the switch current limit isreducedto1/3ofthenominalvalueI . LIMF Due to the short circuit protection is enabled during start-up, the device does not deliver more than 1/3 of its nominal current limit I until the output voltage exceeds 1/3 of the nominal output voltage.

The selected inductor must be rated for its DC resistance and saturation current. The inductor ripple current (ΔI ) decreases with higher inductance and L increaseswithhigherV orV . IN OUT Equation 3 calculates the maximum inductor current in PWM mode under static load conditions. The saturation current of the inductor should be rated higher than the maximum inductor current as calculated with Equation 4.

TI recommends ceramic capacitors with low ESR values that have the lowest output voltage ripple. The output capacitor requires either an X7R or X5R dielectric. Y5V and Z5U dielectric capacitors, aside from their wide variation in capacitance over temperature, become resistive at high frequencies and may not be used. For most applications a nominal 10-µF or 22-µF capacitor is suitable. At small ceramic capacitors, the DC-bias effect decreases the effective capacitance. Therefore a 22-µF capacitor can be used for output voltages higher than2V,seelistofcapacitors.

When the switching waveform shows large duty cycle jitter or the output voltage or inductor current shows oscillations, the regulation loop may be unstable. This is often a result of board layout and/or wrong L-C output filter combinations. As a next step in the evaluation of the regulation loop, the load transient response is tested.

If the layout is not carefully done, the regulator could showpoorlineand/orloadregulation,stabilityissuesaswellasEMIandthermalproblems.Itiscriticaltoprovide a low inductance, impedance ground path. Therefore, use wide and short traces for the main current paths. The inputcapacitorshouldbeplacedascloseaspossibletotheICpinsaswellastheinductorandoutputcapacitor. Connect the AGND and PGND pins of the device to the PowerPAD™ land of the PCB and use this pad as a star point. Use a common power PGND node and a different node for the signal AGND to minimize the effects of ground noise. The FB divider network should be connected right to the output capacitor and the FB line must be routedawayfromnoisycomponentsandtraces(forexample,SWline). Due to the small package of this converter and the overall small solution size the thermal performance of the PCB layout is important. To get a good thermal performance, TI recommends a four or more Layer PCB design. The PowerPAD™ of the IC must be soldered on the power pad area on the PCB to get a proper thermal connection.Forgoodthermalperformancethe PowerPAD™onthePCBneedstobeconnectedtoaninnerGND planewithsufficientviaconnections.Refertothedocumentationoftheevaluationkit. 11.2 Layout Example G P e e/bl da on ME V GND IN V C C IN OUT OUT L R2 R1 C FF D N G Figure28.
