RT7256B Datasheet (Richtek) - Synchronous Step-Down Converter

RT7256B, Synchronous Step-Down Converter

The RT7256B is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 17V input supply.

The RT7256B's current mode architecture and internal compensation allow the transient response to be optimized over a wide input range and load
