TPS62240,TPS62242,TPS62243 www.ti.com SLVS762C–JUNE2007–REVISEDJULY2015 8 Detailed Description 8.1 Overview The TPS6224x step-down converter operates with typically 2.25-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 uses a unique fast response voltage mode control 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 then flows from the input capacitor through the high-side MOSFET switch through the inductortotheoutputcapacitorandload.Duringthisphase,thecurrentrampsupuntilthePWMcomparatortrips and the control logic turns off the switch. The current-limit comparator also turns off the switch if 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 then flows from the inductor to theoutputcapacitorandtotheload.Itreturnsbacktotheinductorthroughthelow-sideMOSFETrectifier. The next cycle is initiated by the clock signal again turning off the low-side MOSFET rectifier and turning on the high-sideMOSFETswitch. 8.2 Functional Block Diagram VIN Current Limit Comparator Thermal Undervoltage VIN Shutdown Lockout1.8V Limit EN High Side PFM Comparator Reference 0.6V VREF FB VREF Only in 2x2SON Control Gate Driver Mode Stage Anti- MODE Shoot-Through ErrorAmp.

Connecting this pin to GND enables the power save mode with an 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. 8.3.3 Enable The device is enabled by setting the EN pin to high. During the start up time t , the internal circuits are Start Up settled and the soft start circuit is activated.

In this J mode, the high-side and low-side MOSFETs are turned off. The device continues its operation when the junction temperaturefallsbelowthethermalshutdownhysteresis. 8.4 Device Functional Modes 8.4.1 SoftStart The TPS6224x has an internal soft-start circuit that controls the ramp up of the output voltage. The output voltage ramps up from 5% to 95% of its nominal value within typical 250 μs. This limits the inrush current in the converter during ramp up and prevents possible input voltage drops when a battery or high impedance power sourceisused.Thesoft-startcircuitisenabledwithinthestart-uptime,t . Startup 8.4.2 PowerSaveMode ThepowersavemodeisenabledwithMODEpinsettolowlevel.Iftheloadcurrentdecreases,theconverterwill enter power save mode operation automatically. During power save mode, the converter skips switching and operateswithreducedfrequencyinPFMmodewithaminimumquiescentcurrenttomaintainhighefficiency. 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 below the PFM comparator threshold of V nominal, the device starts a PFM current pulse. The high-side OUT MOSFETswitchwillturnon,andtheinductorcurrentrampsup.Aftertheon-timeexpires,theswitchisturnedoff andthelow-sideMOSFETswitchisturnedonuntiltheinductorcurrentbecomeszero. 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 to or greater than the PFM comparator threshold,thedevicestopsswitchingandentersasleepmodewithtypical15-μAcurrentconsumption. If the output voltage is still below the PFM comparator threshold, a sequence of further PFM current pulses are generated until the PFM comparator threshold is reached. The converter starts switching again once the output voltagedropsbelowthePFMcomparatorthreshold. 8 SubmitDocumentationFeedback Copyright©2007–2015,TexasInstrumentsIncorporated ProductFolderLinks:TPS62240 TPS62242 TPS62243

Increasing output capacitor values and inductor values will minimize the output ripple. The PFM frequency decreases with smaller inductor values and increases with larger values. If the output current cannot be supported in PFM mode, the device exits PFM mode and enters PWM mode. The power save mode can be disabled through the MODE pin set to high. The converter will then operate in fixed- frequencyPWMmode. Output voltage V nominal OUT PWM+PFM Light load moderate to heavy load PFM Mode PWM Mode Figure5.

The current in the switches is monitored by current-limit comparators. Once the current in the high-side LIMF MOSFET switch exceeds the threshold of its current-limit comparator, it turns off and the low-side MOSFET switch is activated to ramp down the current in the inductor and high-side MOSFET switch. The high-side MOSFET switch can only turn on again, once the current in the low-side MOSFET switch has decreased below thethresholdofitscurrent-limitcomparator.

The device is optimized for operation with a 2.2-μH inductor and 10-μF output capacitor. Larger or smaller inductor values can be used to optimize the performance of the device for specific operation conditions. For stable operation, the L and C values of the output filter may not fall below 1-μH effective inductance and 3.5-μF effective capacitance. Selecting larger capacitors is less critical because the corner frequencyoftheL-Cfiltermovestolowerfrequencieswithfewerstabilityproblems. 9.2.2.2.1 InductorSelection The inductor value has a direct effect on the ripple current. 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 The inductor selection also has an impact on the output voltage ripple in the PFM mode. Higher inductor values will lead to lower output voltage ripple and higher PFM frequency, and lower inductor values will lead to a higher outputvoltageripplebutlowerPFMfrequency. 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. This is recommended because during heavy load transients the inductor current will rise above the calculated value.

LIMF Accepting larger values of ripple current allows the use of low inductance values, but results in higher output voltageripple,greatercorelosses,andloweroutputcurrentcapability.

For most applications, a 4.7-μF to 10-μF ceramic capacitor is recommended. Because ceramic capacitors lose up to 80% of their initial capacitance at 5 V, it is recommended that a 10-μF input capacitor be used for input voltages greaterthan4.5V.Theinputcapacitorcanbeincreasedwithoutanylimitforbetterinputvoltagefiltering. Take care when using only small ceramic input capacitors. When a ceramic capacitor is used at the input, and thepowerisbeingsuppliedthroughlongwires,suchasfromawalladapter,aloadstepattheoutput,orV step IN on the input, can induce ringing at the VIN pin.

Proper function of the device demands careful attention to PCB layout. Care must be taken in board layout to get the specified performance. If the layout is not carefully done, the regulator could show poor line and/or load regulation, and additional stability issues as well as EMI problems. It is critical to provide a low inductance, impedance ground path. Therefore, use wide and short traces for the main current paths. The input capacitor should be placed as close as possible to theICpinsaswellastheinductorandoutputcapacitor. Connect the GND pin of the device to the PowerPAD™ land of the PCB and use this pad as a star point. Use a common power GND node and a different node for the signal GND to minimize the effects of ground noise. Connect these ground nodes together to the PowerPAD land (star point) underneath the IC. Keep the common path to the GND pin, which returns the small signal components, and the high current of the output capacitors as shortaspossibletoavoidgroundnoise.TheFBlineshouldbeconnectedrighttotheoutputcapacitorandrouted awayfromnoisycomponentsandtraces(forexample,theSWline). 11.2 Layout Examples Figure30.
