RT3624PE
RT3624PE is Dual Channel PWM Controller manufactured by Richtek.
Description
The RT3624PE is a synchronous buck controller that supports two output rails and fully meets the Intel IMVP9.1 requirements. The RT3624PE adopts GNAVPTM (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 pensation. The RT3624PE provides VR Ready and thermal indicators. It also features plete fault protection functions, including overvoltage (OV), undervoltage (UV), overcurrent (OC), and undervoltage lockout (UVLO). The remended junction temperature range is from
- 40C to 125C.
