The TPS56124x is a simple, easy-to-use, synchronous buck converter with input voltage ranging from 4.2V to 17V and supports up to 1A 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 TPS561243 operates in Eco-mode, which maintains high efficiency during light load operation. The TPS561246 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. The TPS56124x integrates complete protection including OCP, UVLO, OTP, and UVP with hiccup.

The TPS56124x is available in a 6pin, 1.6mm × 1.6mm SOT563 (DRL) package. The junction temperature is specified from –40°C to 125°C.
