Overview
® RT7238B/C/D/E 8A, 23V, 500kHz 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.
