Hot-selling and scarce TPS62040DRCRG4 1.2 A/1.25 MHz, HIGH-EFFICIENCY STEP-DOWN CONVERTER 10VSON spot stock

Product Descriptions

The  TPS6204x  family  of  devices  are  high  efficiencysynchronous step-down dc-dc converters optimized forbattery powered portable applications . The devices areideal for portable applications powered by a single Li-Ionbattery cell or by 3-cell NiMH/NiCd batteries . With anoutput voltage range from 6.0 V down to 0.7 V,the devicessupport  low  voltage  DSPs  and  processors  in  PDAs,pocket  PCs,  as  well  as  notebooks  and  subnotebookcomputers . The TPS6204x operates at a fixed switchingfrequency of 1.25 MHz and enters the power save modeoperation at light load currents to maintain high efficiencyover  the  entire  load  current  range .  For  low  noiseapplications,  the  devices  can  be  forced  into  fixedfrequency PWM mode by pulling the MODE pin high .TheTPS6204x supports up to 1.2-A load current .
