RT8843C Description
The RT8843C is a 3/2/1 multi-phase synchronous Buck controller optimized for high performance graphic microprocessor, and it support nVidia OVR3i+ spec with PWM-VID interface. It can support both DrMOS with current output and DCR current sensing. The RT8843C adopts AC G-NAVPTM (Green Native AVP), which is Richtek's proprietary topology derived from finite DC gain of internal GM amplifier with current mode control.
