RT8253B Datasheet (Richtek) - 1.2MHz Synchronous Step-Down Converter

RT8253B, 1.2MHz Synchronous Step-Down Converter

The RT8253B is a high-efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from a 4.5V to 23V input supply.

The RT8253B's current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and o
