The TPS56425xx is a simple, easy-to-use, high efficiency, high power density, synchronous buck converter with input voltage ranging from 3V to 17V and supports up to 4A continuous current at output voltages between 0.6V and 10V.

The TPS56425xx employs D-CAP3 control mode to provide a fast transient response and to support low-ESR output capacitors with no requirement for external compensation. The device can support up to 97% duty cycle operation.

The TPS564252B, TPS564252C operates in Eco-mode, which maintains high efficiency during light loading. The TPS564257B, The TPS564257C operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. The TPS564255B operates in OOA mode, which prevents audio noise generation. The devices integrate complete protection through OVP, OCP, UVLO, OTP, and UVP with hiccup.

The device is available in 1.6mm × 1.6mm SOT-563 package. The junction temperature is specified from –40°C to 125°C.
