RT7249 Datasheet (Richtek) - 18V Synchronous Step-Down Converter

RT7249, 18V Synchronous Step-Down Converter

The RT7249 is a high efficiency, monolithic synchronous step-down DC/DC converter with a power switch.

The Buck converter can deliver up to 3A output current from 4.5V to 18V input supply.

The RT7249's current-mode architecture and external compensation allow the transient response to be optimized o
