The RT8166B 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.
complete fault protection functions including over voltage, under voltage, negative voltage, over current and thermal shutdown.
The RT8166B is available in a WQFN-40L 5x5 small footprint package.
