The RT3624PE is a synchronous buck controller that supports two output rails and fully meets the Intel IMVP9.1 requirements. The RT3624PE adopts G-NAVPTM (Green Native AVP), which is Richtek’s proprietary topology derived from the finite DC gain of an EA amplifier with current mode control. This design makes it easy to set the droop to meet all Intel CPU requirements of AVP (Adaptive Voltage Positioning). The RT3624PE integrates a high-accuracy ADC for platform and function settings, such as ICCMAX, switching frequency, DVID fast slew rate, and DVID compensation. The RT3624PE provides VR Ready and thermal indicators. It also features complete fault protection functions, including overvoltage (OV), undervoltage (UV), overcurrent (OC), and undervoltage lockout (UVLO). The recommended junction temperature range is from -40°C to 125°C.
