® RT8172A Dual Single-Phase PWM Controller for CPU and GPU Core Power Supply 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. The RT8172A 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.
