RT9209 Datasheet (Richtek) - Synchronous Buck PWM DC-DC

RT9209, Synchronous Buck PWM DC-DC

The RT9209/A is a single power supply PWM DC-DC converter controller designed to drive N-MOSFET in a synchronous buck topology.

The IC integrates the control, output adjustment, monitoring and protection functions into a small 8-pin package.

The RT9209/A uses an internal compensated voltage mode PWM
