TPS563203, TPS563206 are simple, easy-to-use, 3A synchronous buck converters in a SOT563 package.

The devices are designed to operate with minimum external component counts and designed 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. The device integrates complete protection through OCP, UVLO, OTP, and UVP with hiccup. TPS56320x is available in a 6-pin, 1.6mm × 1.6mm SOT563 (DRL) package and specified from a –40°C to 125°C junction temperature.
