RT6258D
RT6258D is 23V Synchronous Step-Down Converter manufactured by Richtek.
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.
