Dual Output 3-Phase + 2-Phase PWM Controller For CPU and GPU Core Power Supply
General Description
The RT8885A is a dual output 3-phase + 2-phase PWM controller with 3 integrated MOSFET gate drivers and a single SVID interface for CPU and GPU core power supply. This part plies with Intel VR12/IMVP7 Pulse Width Modulation Specification. The RT8885A adopts G-NAVPTM (Green-Native AVP), which is a Richtek proprietary topology derived from finite DC gain pensator in constant ontime control mode. G-NAVPTM makes this part an easysetting PWM controller to meet all Intel mobile CPU/GPU AVP (Active Voltage Positioning) requirements. The RT8885A uses SVID interface to control an...
