RT7257J Datasheet (Richtek) - Synchronous Step-Down Converter

RT7257J, Synchronous Step-Down Converter

The RT7257J 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 RT7257J's current mode architecture and external compensation allow the transient response to be optimized over a wide input voltage range
