RT8848D Multi-Phase PWM Controller

The RT8848D 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 RT8848D adopts AC G-NAVPTM (Green Native AVP), which is Richtek's proprietary topology derived from fini.

RT8848D Features

* external reference input and PWM-VID dynamic output voltage control, in which the output voltage is regulated and tracks external input reference voltage. The RT8848D can set internal RAMP amplitude through PINSETx pin and this can optimize stability and load transient performance. The RT8848D also
