RT8889D Datasheet (Richtek) - 3-Phase PWM Controller

RT8889D, 3-Phase PWM Controller

The RT8889D is a three phase CPU power controller with triple integrated drivers for VR12.5 compliant.

The RT8889D adopts G-NAVPTM (Green Native AVP) which is Richtek's proprietary topology derived from finite DC gain of EA amplifier with current mode control, making it an easy setting the droop to
