The RT3607CJ is an IMVP8 compliant CPU power controller which includes two voltage rails : a 4/3/2/1 phase synchronous Buck controller, the CORE VR, a 3/2/1 phase synchronous Buck controller, the AXG VR. The RT3607CJ adopts G-NAVP^TM(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-NAVP^TM topology, the RT3607CJ also features a quick response mechanism for optimized AVP performance during load transient. The RT3607CJ supports mode transition function with various operating states. A serial VID (SVID) interface is built in the RT3607CJ to communicate with Intel IMVP8 compliant CPU. The RT3607CJ supports VID on-the-fly function with three different slew rates : Fast, Slow and Decay. By utilizing the G-NAVP^TM topology, the operating frequency of the RT3607CJ varies with VID, load and input voltage to further enhance the efficiency even in CCM. Moreover, the G-NAVP^TM 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 RT3607CJ integrates a high accuracy ADC for platform setting functions, such as quick response trigger level or over-current level. Besides, the setting function also supposes this two rails address exchange. The RT3607CJ 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 RT3607CJ is available in the WQFN-56L 6x6 small foot print package.
