General Description

The RT8172A is a dual single-phase PWM controller with integrated MOSFET drivers, compliant with Intel IMVP7 Pulse Width Modulation Specification to support both CPU core and GPU core power.

This part adopts G-NAVPTM (Green-Native AVP), which is Richtek's proprietary topology derived from finite DC gain compensator in constant ontime control mode.

The G-NAVPTM makes this part an easy setting PWM controller to meet all Intel AVP (Active Voltage Positioning) mobile CPU/GPU requirements.

Key Features

  • complete fault protection functions including over-voltage, under-voltage, negative-voltage, over-current and thermal shutdown. The RT8172A is available in the WQFN-40L 5x5 small footprint package. Features.
