3.Description

TheTPS6040x-Q1familyof devicesgenerateanunregulatednegativeoutputvoltagefroman inputvoltagerangingfrom1.8 V to 5.25V. The devicesaretypicallysuppliedby a preregulatedsupplyrail of 5 Vor 3.3 V. Dueto its wide-inputvoltagerange,two orthreeNiCd,NiMH,or alkalinebatterycells,as well asone Li-Ioncell, can also powerthem.
Onlythreeexternal1-μF capacitorsare requiredtobuilda completeDC-DCchargepumpinverter.Assembledin a 5-pinSOT-23package,the completeconvertercanbe builton a 50-mm2boardarea.Replacingthe Schottkydiodetypicallyneededforstart-upinto loadwith integratedcircuitrycan achieveadditionalboardareaandcomponentcountreduction.
TheTPS6040x-Q1can delivera maximumoutputcurrentof 60 mA, with a typicalconversionefficiencyof greaterthan90%overa wideoutputcurrentrange.ThreedeviceoptionsTPS60401/2/3-Q1with 20-kHz,50-kHz,and 250-kHzfixedfrequencyoperationareavailable.TPS60400-Q1devicecomeswithavariableswitchingfrequencyto reduceoperatingcurrentin applicationswitha wideloadrangeandenablesthe designwith low-valuecapacitors
