RT3672EE
2-Phase PWM Controller with I2C Interface Control for AMD SVI3 Power Supply
General Description
The RT3672EE is a synchronous buck controller that supports single output rail and fully meets AMD SVI3 requirements. The RT3672EE 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 RT3672EE features a new generation of quick response mechanism (Adaptive Quick Response, AQR) to optimize AVP performance during load transient and to reduce output capacitors.
