RT7297A Datasheet (Richtek) - Synchronous Step-Down Converter

RT7297A, Synchronous Step-Down Converter

The RT7297A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 18V input supply.

The RT7297A's current mode architecture and external compensation allow the transient response to be optimized over a wide input voltage range
