RT7274 Datasheet (Richtek) - Synchronous Step-Down Converter

RT7274, Synchronous Step-Down Converter

The RT7274/79/80/81 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 2A output current from a 4.5V to 18V input supply.

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