Texas Instruments TPS563202

Description

TPS563202 is a simple, easy-to-use, 3-A synchronous buck converter in a SOT563 package.The device is optimized to operate with minimum external component counts and also optimized to achieve low standby current.This switch mode power supply (SMPS) device employs D-CAP2 mode control providing a fast transient response and supporting both low-equivalent series resistance (ESR) output capacitors such as specialty polymer and ultra-low ESR ceramic capacitors with no external compensation components.TPS563202 operates in ECO mode, which maintains high efficiency during light load operation. TPS563202 is available in a 6-pin 1.6-mm × 1.6-mm SOT563 (DRL) package, and specified from a –40°C to 125°C junction temperature.
