RT7251A Datasheet (Richtek) - Synchronous Step-Down Converter

RT7251A, Synchronous Step-Down Converter

The RT7251A/B is a high efficiency, monolithic synchronous step-down DC-DC converter that can operate at 340kHz/800kHz, while delivering up to 1.5A output current from a 4V to 17V input supply.

The RT7251A/B's current mode architecture allows the transient response to be optimized.
