1. Description
TPS61021ADSGR provides a power solution for Portable or smart devices powered by alkaline or nickel-metal hydride batteries Lithium manganese or lithium ion battery. TPS61021A has Schematic diagram of outputting 3.3V voltage and 1.5A current from A The battery is discharged to as low as 1.8V. When the input voltage is 0.5V, TPS61021A can extend battery runtime. TPS61021A operates at a switching frequency of 2MHz Frequency under heavy load and enter energy saving mode Maintain high efficiency of the entire system under light load Load current range. The device only consumes 17- Under light load conditions, the quiescent current of VOUT is μA. During shutdown, the load is completely disconnected From the input. In addition, TPS61021ADSGR also provides 4.35-V output overvoltage protection, output short circuit Circuit protection and thermal shutdown protection. TPS61021ADSGR provides a very small solution size The number of external components is small. It allows to use 2 small inductors and output capacitor MHz switching frequency. The size of TPS61021ADSGR is 2.0 mm x 2.0 mm WSON software package.
