RT3635BE中文资料Triple Channel PWM Controller with I2C Interface Control for IMVP9.2 CPU Core Power Supply数据手册Richtek规格书

描述 Description

The RT3635BE is an IMVP9.2 compliant CPU power controller which includes three voltage rails: a 5-phase synchronous buck controller for VCCCORE VR, a 2-phase 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 5 phases for VCCCORE, 2 phases for VCCGT and 1 phase for VCCSA. For example, the RT3635BE supports output operations of 5+2+1, 4+2+1, 3+2+1, etc. The RT3635BE 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 RT3635BE 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 RT3635BE features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. The RT3635BE 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 RT3635BE offers built-in non-volatile memory (NVM) for platform setting functions, such as ICCMAX, switching frequency or AQR trigger level. The RT3635BE provides VR ready output signals. It also features complete fault protection functions including overvoltage (OV), overcurrent (OC), undervoltage (UV) and undervoltage lockout (UVLO). The RT3635BE is available in the WQFN-60L 7x7 footprint package.
