Overview
® RT8884C Multi-Phase PWM Controller for CPU Core Power Supply General Description 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).
Based on the GNAVPTM topology, the RT8884C also features a quick response mechanism for optimized AVP performance during load transient.
The RT8884C supports mode transition function with various operating states.
A Serial VID (SVID) interface is built in the RT8884C to communicate with Intel VR12.
5 compliant CPU.
The RT8884C supports VID on-the-fly function with three different slew rates : Fast, Slow and Decay.
By utilizing the G-NAVPTM topology, the operating frequency of the RT8884C varies with VID, load current and input voltage to further enhance the efficiency even in CCM.
Besides G-NAVPTM, the CCRCOT (Constant Current Ripple Constant On Time) technology provides superior output voltage ripple over the entire input/output range.
