RT3672EE Datasheet | Richtek

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. The RT3672EE 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), overcurrent (OC), undervoltage lockout (UVLO), over-temperature protection (OTP), VR-hot warning, CRC failure and munication failure. The RT3672EE provides enable, power good and temperature sensing. It also supports functions that can be set by the I2C interface.
