RT3674FE - Triple Channel PWM Controller

Datasheet Summary

Description

The RT3674FE is a synchronous buck controller which supports triple 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 RT3674FE 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 complete fault protection functions including overvoltage (OV), undervoltage (U.

RT3674FE Triple Channel PWM Controller for AMD SVI3 CPU/GPU Core Power Supply 1 General Description The RT3674FE is a synchronous buck controller which supports triple output rails and can fully meet AMD SVI3 requirements. The RT3674FE adopts GNAVPTM (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 RT3674FE features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and reduce output capacitors.
