Multi-Phase PWM Controller for CPU Core Power Supply
General Description
The RT8884B is a 4/3/2/1 multi-phase synchronous Buck controller designed to meet Intel VR12.5 patible CPU specification with a serial VID control interface. The RT8884B 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). Based on the GNAVPTM topology, the RT8884B also Features a quick response mechanism for optimized AVP performance during load transient. The RT8884B supports mode transition function with...
