TPS563203, TPS563206 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-CAP3 control mode 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.

TPS563203 operates in ECO mode, which maintains high efficiency during light load operation. TPS563206 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. It integrates complete protection through OCP, UVLO, OTP, and UVP with hiccup. TPS56320x 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.
