RT6318B
RT6318B is 23V Synchronous Step-Down Converter manufactured by Richtek.
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.
