RT7277 Datasheet (Richtek) - Synchronous Step-Down Converter

RT7277, Synchronous Step-Down Converter

The RT7277 is a synchronous step-down DC/DC converter with Advanced Constant On-Time (ACOTTM) mode control.

It achieves high power density to deliver up to 3A output current from a 4.5V to 18V input supply.

The proprietary ACOTTM mode offers an optimal transient response over a wide range of loads a
