Richtek Technology RT3634CE
The RT3634CE is an IMVP9.2 compliant CPU power controller which includes three voltage rails: a 4-phase synchronous buck controller for VCCCORE VR, a 3phase synchronous buck controller for VCCGT VR, and a 1-phase synchronous buck controller for VCCSA VR. The output of each rail can be configured to support the desired phase assignments up to a maximum phase count of 4 phases for VCCCORE, 3 phases for VCCGT and 1 phase for VCCSA. For example, the RT3634CE supports output operations of 4+3+1, 4+2+1, 3+2+1, etc.

GENERAL DESCRIPTION
The RT3634CE adopts the Smart Phase Management (SPM) feature, to achieve maximum efficiency in all load range. Thresholds for automatic phase add/drop are user-programmable using I2C protocol interface. The RT3634CE 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 RT3634CE features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. The RT3634CE supports mode transition function with various operating states. A serial VID (SVID) interface is built in to communicate with Intel IMVP9.2 compliant CPU. The RT3634CE offers built-in non-volatile memory (NVM) for platform setting functions, such as ICCMAX, switching frequency or AQR trigger level.
