Dual Channel PWM Controller for IMVP8 CPU Core Power Supply
The RT3606BE is an IMVP8 compliant CPU power controller which includes two ,voltage rails : a 3/2/1 phase synchronous Buck controller, the CORE VR and a ,2/1 phase synchronous Buck controller, the AXG VR. The RT3606BE 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 G-NAVPTM topology, the RT3606BE also features a quick response ,mechanism for optimized AVP performance during load transient. The RT3606BE ,supports mode transition function with various operating states. A serial VID ,(SVID) interface is built in the RT3606BE to communicate with Intel IMVP8 ,compliant CPU. The RT3606BE 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 RT3606BE varies with VID, load and ,input voltage to further enhance the efficiency even in CCM. Moreover, the ,G-NAVPTM with CCRCOT (Constant Current Ripple COT) technology provides superior ,output voltage ripple over the entire input/output range. The built-in high ,accuracy DAC converts the SVID code ranging from 0.25V to 1.52V with 5mV per ,step. The RT3606BE integrates a high accuracy ADC for platform setting ,functions, such as quick response trigger level or over-current level. Besides, ,the setting function also supports this two rails address exchange. The ,RT3606BE provides VR ready output signals. It also features complete fault ,protection functions including over-voltage (OV), negative voltage (NV), ,over-current (OC) and under-voltage lockout (UVLO). The RT3606BE is available ,in the WQFN-48L 6x6 small foot print package.
