Preliminary
RT3624BE
Dual Channel PWM Controller for IMVP9.1 CPU Core Power Supply
General Description
The RT3624BE is a synchronous buck controller which supports 2 output rails and can fully meet Intel IMVP9.1 requirements. The RT3624BE 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 RT3624BE features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors.
