Multi-Phase PWM Controller for CPU Core Power Supply
General Description
The RT8859M is a VR12/IMVP7 pliant 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 pensator 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. The...
