RT7238D Overview
The RT7238B/C/D/E is an advanced constant on-time (ACOTTM) mode synchronous step-down converter. The main control loop of RT7238B/C/D/E using an advanced constant on-time (ACOTTM) mode control which provides a very fast transient response. The RT7238B/C/D/E operates from 8V to 23V input voltage.
