RT3678BE - Dual Channel PWM Controller

Description

The RT3678BE is a synchronous buck controller which supports dual output rails and can fully meet AMD SVI3 requirements.

Features

  • a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors. The RT3678BE integrates a high accuracy ADC for reporting and a non-volatile memory (NVM) to store custom configurations, such as output current scale, auto phase add/drop threshold, switching frequency, overcurrent threshold or AQR trigger level. It also features full fault protection functions, including overvoltage (OV), undervoltage (UV),.

RT3678BE Dual Channel PWM Controller with I2C Interface Control for AMD SVI3 CPU/GPU Core Power Supply General Description The RT3678BE is a synchronous buck controller which supports dual output rails and can fully meet AMD SVI3 requirements. The RT3678BE 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 AMD CPU/GPU requirements of AVP (Adaptive Voltage Positioning). Based on the G-NAVPTM topology, the RT3678BE features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors.
