RT7238C Datasheet | Richtek

® RT7238B/C/D/E 8A, 23V, 500k Hz Synchronous Step-Down Converter with 3.3V/5V LDO General Description 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. For the RT7238D, the output voltage can be adjusted between 0.6V to 5V.
