General Description

The RT3612EB is a 2/1 phase synchronous buck controller designed to meet Intel IMVP9 compatible CPU specification with a serial VID control interface.

The RT3612EB 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 RT3612EB

Overview

® RT3612EB 2-Phase PWM Controller with Dual Integrated Drivers for IMVP9 CPU Core Power Supply.

Key Features

  • a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. The RT3612EB supports mode transition function with various operating states. A serial VID (SVID) interface is built in the RT3612EB to communicate with Intel IMVP9 compliant CPU. The RT3612EB supports VID on-the-fly function with three different slew rates: Fast, Slow and Decay. By utilizing the G-NAVPTM topology, the operating frequency of.
