Overview
RT8848A/B Multi-Phase PWM Controller with PWM-VID Reference General Description The RT8848A/B is a 8/7/6/5/4/3/2/1 multi-phase synchronous Buck controller which is optimized for high performance graphic microprocessor and support nVidia OVR4i+ spec with PWM-VID interface.
The RT8848A/B 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 RT8848A/B varies with VID, load and input voltage to further enhance the efficiency even in CCM.
Besides, for current sensing application, the RT8848A/B can support either a tradition...
