RT6258D - 23V Synchronous Step-Down Converter

Datasheet Summary

Description

The RT6258D is an advanced constant on-time (ACOTTM) mode synchronous buck converter.

The main control loop of the RT6258D uses an advanced constant on-time (ACOTTM) mode control which provides a very fast transient response.

The RT6258D operates from 5.1V to 23V input voltage.
