Texas Instruments  TPS61021EVM-723

The TPS61021A provides a power supply solution for portable devices and IoT devices powered by alkaline battery or LiMn battery. The TPS61021A supports up to 1.5A load current from a battery discharged as low as 1.8V. The TPS61021A operates at a regulated 2.0-MHz switching frequency and enters power-save mode operating at light load currents to maintain high efficiency over the entire load current range. During shutdown, the load is completely disconnected from the battery.
