RT6258B
RT6258B is 23V Synchronous Step-Down Converter manufactured by Richtek.
Description
The RT6258B/C is an advanced constant on-time (ACOT®) mode synchronous buck converter. The main control loop of the RT6258B/C using an advanced constant on-time (ACOT®) mode control which provides a very fast transient response. The RT6258B operates from 4.5V to 23V input voltage and the RT6258C operates from 5.1V to 23V.
