General Description

The RT6318B/C is an advanced constant on-time

(ACOT®) mode synchronous buck converter. The main

control loop of the RT6318B/C using an advanced constant

on-time (ACOT®) mode control which provides a very fast

transient response. The RT6318B operates from 4.5V to

23V input voltage and the RT6318C operates from 5.1V

to 23V.
