Overview
® RT8859M Multi-Phase PWM Controller for CPU Core Power Supply General Description The RT8859M is a VR12/IMVP7 compliant CPU power controller which includes two voltage rails : a 4/3/2/1 phase synchronous buck controller, the CORE VR, and a single phase buck controller, the AXG VR.
The RT8859M adopts G-NAVP TM (Green Native AVP), which is Richtek's proprietary topology derived from finite DC gain compensator with current mode control, making it an easy setting PWM controller, meeting all Intel CPU requirements of AVP (Active Voltage Positioning).
Based on the G-NAVPTM topology, the RT8859M also features a quick response mechanism for optimized AVP performance during load transient.
