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.
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 RT8848A/B can set internal RAMP amplitude through PINSETx pin and this can optimize stability and load transient performance. The RT8848A/B also provides complete fault protection functions including over-voltage protection (OVP), under-voltage protection (UVP), channel over-current limit (CH_OC), sum output current protection (SOC) and ov.
