User's Guide SLVU659A –March 2012–RevisedMarch 2012 TPS62125EVM-044 EvaluationModule Thisuser’s guidedescribesthecharacteristics,operation,and use oftheTexas InstrumentsTPS62125 evaluationmodule (EVM). ThisEVM isdesignedtohelptheusereasilyevaluateand testtheoperation and functionalityof the TPS62125. The EVM convertsa 4-V to 17-V inputvoltageto a regulated3.3-V outputvoltagethatdelivers300 mA. This user’s guide includessetup instructionsforthe hardware, printed-circuitboardlayoutsfortheEVM, a schematicdiagram,a billofmaterials,and testresultsforthe EVM.

1 Introduction

The TPS62125 isa 300-mA, synchronous,step-downconverterina 2x2-mm, 8-pinWSON package.

1.1 Background

The TPS62125EVM-044 (PWR044) uses theTPS62125 deviceand issettoa 3.3-Voutput.The EVM operateswithfull-ratedperformancewithan inputvoltagebetween 4 V and 17 V,assumingJP1 is connectedbetween ON and EN. The TPS62125 devicecontainsan adjustableenablethresholdand adjustablehysteresisfeature.Thus, theinputvoltageatwhichthedeviceenablesand disablesisfullyprogrammableby theuser.Inthe TPS62125EVM-044, thedeviceissettoturnon at6 V and turnoffat4 V.Thisfeaturecan be bypassed by usingjumperJP1,whichoverridestheprogrammed thresholdvoltages.

1.2 Performance Specification

Table1 providesa summary oftheTPS62125EVM-044 performancespecifications.Allspecificationsare givenforan ambienttemperatureof25°C. Table1.Performance SpecificationSummary Specification TestConditions Min Typ Max Unit Inputvoltage JP1 connectedbetween EN and ON 4 17 V Outputvoltage PWM Mode ofOperation 3.3 V Outputcurrent 0 300 mA Peak efficiency 93.3% Soft-starttime Ramp timeoftheoutputvoltage 330 µs

1.3 Modifications

The printed-circuitboard(PCB) forthisEVM accommodates additionalinputand outputcapacitors,as well as a feedforwardcapacitor.

1.3.1 Inputand Output Capacitors

C3 isprovidedforan additionalinputcapacitor.Thiscapacitorisnotrequiredforproperoperationbutcan be used toreducetheinputvoltageripple. C4 isprovidedforan additionaloutputcapacitor.Thiscapacitorisnotrequiredforproperoperationbut can be used toreducetheoutputvoltagerippleand toimprovetheloadtransientresponse.The total outputcapacitancemust remainwithintherecommended rangeinthedatasheetforproperoperation.

1.3.2 Feedforward Capacitor

C6 isprovidedfora feedforwardcapacitor.Thiscapacitorisnotrequiredforproperoperationbutcan be used toimprovethetransientresponse.Typically,usinga 22-pFfeedforwardcapacitorreducesor eliminatesany outputvoltageovershootthatmay occuratstart-up.C6 islocatedon theback sideofthe PCB.
