The RT3601EAGQW is an IMVP8 compliant CPU power controller with 1 embedded driver. The RT3601EAGQW 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 RT3601EAGQW also features a quick response mechanism for optimized AVP performance during load transient. The RT3601EAGQW supports mode transition function with various operating states. A serial VID (SVID) interface is built in the RT3601EAGQW to communicate with Intel IMVP8 compliant CPU. The RT3601EAGQW 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 RT3601EAGQW 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 RT3601EAGQW integrates a high accuracy ADC for platform setting functions, such as quick response trigger level. Besides, the setting function also supposes this two rails address exchange. The RT3601EAGQW 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 RT3601EAGQW is available in the WQFN-28L 4x4 small foot print package.
