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.

Key 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 RT8848C can set internal RAMP amplitude through PINSETx pin and this can optimize stability and load transient performance. The RT8848C also provides complete fault protection functions including overvoltage protection (OVP), undervoltage protection (UVP), channel overcurrent limit (CH_OC), sum output current protection (SOC) and over-temp.
