RT6254A Datasheet (Richtek) - Step-Down Converter

RT6254A, Step-Down Converter

The RT6254A/B is a high-performance, synchronous stepdown DC-DC converter that can deliver up to 4A output current from a 4.5V to 18V input supply.

The device integrates low RDS(ON) power MOSFETs, accurate 0.6V reference and an integrated diode of bootstrap circuit to offer a very compact solution.
