TPS62080,TPS62080A,TPS62081,TPS62082 SLVSAE8F–SEPTEMBER2011–REVISEDNOVEMBER2016 www.ti.com 8 Detailed Description 8.1 Overview The TPS6208x synchronous switched mode converters are based on DCS-Control™ (Direct Control with Seamless transition into Power Save Mode). This is an advanced regulation topology that combines the advantagesofhysteretic,voltageandcurrentmodecontrol. The DCS-Control topology operates in pulse width modulation (PWM) mode for medium to heavy load conditions and in Power Save Mode at light load currents. In PWM mode, the converter operates with its nominal switching frequency of 2 MHz having a controlled frequency variation over the input voltage range. As the load current decreases, the converter enters Power Save Mode, reducing the switching frequency and minimizing the IC quiescent current to achieve high efficiency over the entire load current range. DCS-Control supports both operationmodes(PWMandPFM)usingasinglebuildingblockhavingaseamlesstransitionfromPWMtoPower Save Mode without effects on the output voltage. Fixed output voltage versions provide smallest solution size combined with lowest no load current consumption. The TPS6208x offers both excellent DC voltage and superior loadtransientregulation,combinedwithverylowoutputvoltageripple,minimizinginterferencewithRFcircuits. The device is equipped with Snooze Mode functionality, which is enabled with the MODE pin. Snooze Mode supports high efficiency conversion at lowest output currents below 2 mA. If no load current is drawn, the ultra low quiescent current of 6.5 µA is sufficient to maintain the output voltage. This extends battery run time by reducing the quiescent current during lowest or no load conditions in battery-driven applications. For mains- operated voltage supplies, Snooze Mode reduces the system's stand-by energy consumption. During shutdown (EN=LOW),thedevicereducesenergyconsumptiontolessthan1 µA. 8.2 Functional Block Diagrams MODE VIN High Side Power N-MOS Good PG 50 Gate Control Driver Logic SW Low Side N-MOS Active Output Discharge Thermal Snooze Mode Shutdown GND EN Softstart ramp direct control comparator VOS & compensation Under Voltage FB Lockout error minimum amplifier on-timer REF DCS-CONTROLTM Copyright © 2016,Texas Instruments Incorporated Figure5.

The PG pin is an open drain output and can sink up to 0.5 mA. The power good output requires a pull-up resistor. When the device is off due to disable, UVLO or thermal shutdown, the PG pin is high impedance (see Table 1).

In this mode, the high-side MOSFET switch is constantly turned on and the low-side MOSFET is switched off. This is particularly useful in battery powered applications to achieve longest operation time by taking full advantage of the whole batteryvoltagerange.Theminimuminputvoltagetomaintainanoutputvoltageiscalculatedas: V = V +I ´(R +R ) IN,MIN OUT OUT,MAX DS(on) L where • V =Minimuminputvoltage IN,MIN • I =Maximumoutputcurrent OUT,MAX • R =High-sideFETON-resistance DS(on) • R =Inductorohmicresistance (1) L 8.3.3 OutputDischarge The output gets discharged by the SW pin with a typical discharge resistor of R whenever the device shuts DIS down.Thisisthecasewhenthedevicegetsdisabledbyenable,thermalshutdown,orundervoltagelockout.The TPS6208AdiffersfromtheTPS62080onlyinitsstrongerdischarge. 8.3.4 Soft-Start WhenENissettostartdeviceoperation,thedevicestartsswitchingafteradelayofabout40 μsandVOUTrises with a slope of about 10mV/μs (See Figure 27 andFigure 29 for typical startup operation). This avoids excessive inrush current and creates a smooth output voltage rise slope. It also prevents excessive voltage drops of primarycellsandrechargeablebatterieswithhighinternalimpedance. If the output voltage is not reached within the soft start time, such as in the case of heavy load, the converter enters regular operation. Consequently, the inductor current limit operates as described below. The TPS6208x is able to start into a pre-biased output capacitor. The converter starts with the applied bias voltage and ramps up theoutputvoltagetoitsnominalvalue. 8.3.5 UndervoltageLockout To avoid mis-operation of the device at low input voltages, an undervoltage lockout is implemented that shuts downthedeviceatvoltageslowerthanV witha120mVtypicalhysteresis.

Excessive current might occur with a shorted/saturated inductor or a heavy load/shortedoutputcircuitcondition. The incorporated inductor peak current limit measures the current in the high-side and low-side power MOSFET. Once the high-side switch current limit is tripped, the high-side MOSFET is turned off and the low-side MOSFET is turned on to reduce the inductor current. When the inductor current drops down to the low-side switch current limit, the low-side MOSFET is turned off and the high-side switch is turned on again. This operation repeats until the inductor current does not reach the high-side switch current limit. Due to internal propagation delays, the real currentlimitvaluecanexceedthestaticcurrentlimitinElectricalCharacteristics. 10 SubmitDocumentationFeedback Copyright©2011–2016,TexasInstrumentsIncorporated ProductFolderLinks:TPS62080 TPS62080A TPS62081 TPS62082

Accordingly, a logic LOW disables the device. If the device is enabled, the internal power stage starts switching and regulates the output voltage to the programmedthreshold.TheENinputmustbeterminatedandnotleftfloating. 8.4.2 PowerSaveMode Astheloadcurrentdecreases,theTPS6208xentersPowerSaveModeoperation.DuringPowerSaveMode,the converter operates with reduced switching frequency in PFM mode and with a minimum quiescent current maintaining high efficiency. Power Save Mode occurs when the inductor current becomes discontinuous. It is based on a fixed on time architecture. The typical on time is given by t = 500 ns × (V /V ). The switching on OUT IN frequencyoverthewholeloadcurrentrangeisshowninFigure21andFigure22. 8.4.3 SnoozeMode The TPS6208x offers a Snooze Mode function. If Snooze Mode is enabled by an external logic signal setting the MODE pin to HIGH, the device's quiescent current consumption is reduced to typically 6.5 µA. As a result, the high efficiency range is extended towards the range of lowest output currents below 2 mA. See the efficiency figuresinApplicationCurves. If the device is operating in Snooze Mode, a dedicated, low power consuming block monitors the output voltage. All other control blocks are snoozing during that time. If the output voltage falls below the programmed output voltage by 3.5% (typ), the control blocks wake up, regulate the output voltage and allow themselves to snooze again until the output voltage drops again. Snooze Mode operation provides a clear efficiency improvement at lowest output currents. If the load current increases, the advantage of efficiency in Snooze mode is reduced. Because the dynamic load regulation operates best if Snooze Mode is disabled, it is recommended to turn off SnoozeModewhentheloadcurrentexceeds2mA.Generally,amicrocontrolleroperatestheMODEpin.

A low ESR multilayer ceramic capacitor is recommended for best filtering and should be placed between VIN and GND as close as possible to those pins. For most applications 10 μF is sufficient, though a largervaluereducesinputcurrentripple. The architecture of the TPS6208X allows the use of tiny ceramic output capacitors with low equivalent series resistance (ESR). These capacitors provide low output voltage ripple and are recommended. To keep its resistance up to high frequencies and to get narrow capacitance variation with temperature, it's recommended to use X7R or X5R dielectric. The TPS6208x is designed to operate with an output capacitance of 10 µF to 100 µF and beyond, as outlined in Table 4. Load transient testing and measuring the bode plot are good ways to verify stabilitywithlargercapacitorvalues.

Ensure that the inputpowersupplyhasasufficientcurrentratingfortheapplication. 11 Layout 11.1 Layout Guidelines ThePCBlayoutisanimportantsteptomaintainthehighperformanceoftheTPS6208xdevices. The input/output capacitors and the inductor should be placed as close as possible to the IC. This keeps the traces short. Routing these traces direct and wide results in low trace resistance and low parasitic inductance. A common power GND should be used. The low-side of the input and output capacitors must be connected properlytothepowerGNDtoavoidaGNDpotentialshift. The sense traces connected to the FB and VOS pins are signal traces. Special care should be taken to avoid noise being induced. By a direct routing, parasitic inductance can be kept small. GND layers might be used for shielding.KeepthesetracesawayfromSWnodes. 11.2 Layout Example space L1 VOUT VIN C1 VIN SW PG VOS C2 GND EN GND MODE FB GND R1 R2 Figure31.
