General Description

The RT3605BE is an IMVP8 compliant CPU power controller which includes three voltage rails : a 3/2/1 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 RT3605BE 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 RT3605BE also

Key Features

  • a quick response mechanism for optimized AVP performance during load transient. The RT3605BE supports mode transition function with various operating states. A serial VID (SVID) interface is built in to communicate with Intel IMVP8 compliant CPU. The RT3605BE supports VID onthe-fly function with three different slew rates : Fast, Slow, and Decay. By utilizing the G-NAVPTM topology, the operating frequency of the RT3605BE varies with VID, load, and input voltage to further enhance the efficiency.
