RT7291B - Synchronous Buck Converter

The RT7291A/B is a synchronous Buck converter with Advanced Constant On-Time (ACOT®) mode control. The main control loop of the RT7291A/B uses an ACOT® mode control which provides a very fast transient response with no external compensators. The RT7291A/B operates from 5V to 23V input voltage, provi.
