RT8165B - Richtek

RT8165B Dual Single-Phase PWM Controller

The RT8165B 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 ontime control mode. G-NAVPTM m.
