Texas Instruments  XTPS563202DRLR

TPS563202 is a simple, easy-to-use, 3-A synchronous buck converter in a SOT563package.

The device is optimized to operate with minimum external component counts and alsooptimized to achieve low standby current.

This switch mode power supply (SMPS) device employs D-CAP2 mode control providing a fasttransient response and supporting both low-equivalent series resistance (ESR) output capacitorssuch as specialty polymer and ultra-low ESR ceramic capacitors with no external compensationcomponents.

TPS563202 operates in ECO mode, which maintains high efficiency during light loadoperation. TPS563202 is available in a 6-pin 1.6-mm × 1.6-mm SOT563 (DRL) package, and specifiedfrom a –40°C to 125°C junction temperature.
