SLVSDM0 June 2016 TPS61021A
The TPS61021A provides a power supply solution for portable or smart devices powered by alkaline, NiMH, Li-Mn, or Li-ion batteries. The TPS61021A is capable of outputting 3.3-V voltage and 1.5-A current from a battery discharged to as low as 1.8 V. Capable of operating with 0.5-V input voltage enables the TPS61021A to extend the battery run time.
The TPS61021A operates at 2-MHz switching frequency at heavy load and enters power-save mode at light load to maintain high efficiency over the entire load current range. The device only consumes a 17-μA quiescent current from VOUT in light load condition. During shutdown, the load is completely disconnected from the input. In addition, The TPS61021A provides 4.35-V output overvoltage protection, output short circuit protection, and thermal shutdown protection.
The TPS61021A offers a very small solution size due to low count of external components. It allows the use of small inductors and output capacitors with the 2-MHz switching frequency.
The TPS61021A is available in 2.0-mm x 2.0-mm WSON package.
