The TPS56224xx is a simple, easy-to-use, synchronous buck converter with input voltage ranging from 4.2V to 17V (TPS562243, TPS562246) and 4.5V to 17V (TPS562246B),, and supports up to 2A continuous current.

The device is designed to operate with minimum external component counts and 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.

The TPS562243 operates in Eco-mode, which maintains high efficiency during light load operation. The TPS562246 and TPS562246B operate in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. The TPS56224xx integrates complete protection including OCP, UVLO, OTP, and UVP with hiccup.

The TPS56224xx is available in a 6pin, 1.6mm × 1.6mm SOT563 (DRL) package. The junction temperature is specified from –40°C to 125°C.
