RT3601BH
Description
The RT3601BH is an IMVP8 compliant CPU power controller which includes three voltage rails : a single phase synchronous Buck controller, the main VR, a 2/1 phase synchronous Buck controller, the auxiliary VR, and a single phase synchronous Buck controller, the VCCSA VR. The RT3601BH 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).
