RT3613EB
3-Phase PWM Controller with Dual Integrated Drivers for IMVP9 CPU Core Power Supply
General Description
The RT3613EB is a 3/2/1 phase synchronous buck controller designed to meet Intel IMVP9 compatible CPU specification with a serial VID control interface. The RT3613EB 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 RT3613EB features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors.
