RT8884C
Overview
The RT8884C is a 4/3/2/1 multi-phase synchronous Buck controller designed to meet Intel VR12.5 compatible CPU specification with a serial VID control interface. The RT8884C 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 easy to set the droop to meet all Intel CPU requirements of AVP (Adaptive Voltage Positioning).
