RT8167BGQW

General Description
The RT8167B 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 a Richtek proprietary topology derived from finite DC gain compensator in constant on time control mode. G-NAVPTM makes this part an easy setting PWM controller to meet all Intel AVP (Active Voltage Positioning) mobile CPU/GPU requirements.
The RT8167B uses SVID interface to control an 8-bit DAC for output voltage programming.
The built-in high accuracy DAC converts the received VID code into a voltage value ranging from 0V to 1.52V with 5mV step voltage.
