RT8120E - Richtek

RT8120E Single-Phase Synchronous Buck PWM Controller

The RT8120E/F is a single-phase synchronous buck PWM DC-DC controller designed to drive two N-MOSFET. It provides a highly accurate, programmable output voltage precisely regulated to low voltage requirements with an internal 0.8V ±1% ( option for 0.6V ±1.5%) reference. The RT8120E/F uses a single feedback loop voltage mode PWM control for fast transient res.
