RT8843C Datasheet | Richtek

Multi-Phase PWM Controller with PWM-VID Reference General 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. By utilizing the AC G-NAVPTM topology, the operating frequency of the RT8843C varies with VID, load and input voltage to further enhance the efficiency even in CCM. Moreover, the AC G-NAVPTM with...
