Overview
RT8848C Multi-Phase PWM Controller with PWM-VID Reference 1 General Description The RT8848C is a 8/7/6/5/4/3/2/1 multi-phase synchronous Buck controller which is optimized for high-performance graphic microprocessor and supports nVidia OVR4i+ spec with PWM-VID interface.
The RT8848C 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 RT8848C varies with VID, load and input voltage to further enhance the efficiency even in CCM.
Besides, for current sensing application, the RT8848C can support either a traditional DCR...
