RT8109 Datasheet (Richtek) - 5V to 12V Single Synchronous Buck PWM Controller

RT8109, 5V to 12V Single Synchronous Buck PWM Controller

The RT8109 is a single-phase synchronous buck PWM DC-DC controller designed to drive two N-MOSFETs.

It provides a highly accurate, programmable output voltage precisely regulated to low voltage requirement with an internal 0.6V ±1% reference.

The RT8109 uses a single feedback loop voltage mode PWM c
