RT8109 Datasheet - Richtek

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.
