General Description

The RT8843C is a 3/2/1 multi-phase synchronous Buck controller optimized for high performance graphic microprocessor, and it support nVidia OVR3i+ spec with PWM-VID interface.

It can support both DrMOS with current output and DCR current sensing.

The RT8843C 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.

Overview

RT8843C Multi-Phase PWM Controller with PWM-VID Reference General.

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 RT8843C can set internal RAMP amplitude through PINSETx pin, which optimizes stability and load transient performance. The RT8843C also provides complete fault protection functions including Overvoltage Protection (OVP), Undervoltage Protection (UVP), Overcurrent Limit (OCL) and Over-Temperature Protection (OTP). Features.
Multi-Phas.
