The TPS56x24x 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 2A (TPS562242B), 3A (TPS563242, TPS563247) continuous current at output voltages between 0.6V and 10V.

The TPS56x24x 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 95% duty cycle operation.

The TPS562242B and TPS563242 operate in Eco-mode, which maintains high efficiency during light loading. The TPS563247 operates in FCCM mode, which keeps the same frequency and lower output ripple during all load conditions. 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.
