General Description

The RT8816A is a 2/1-phase synchronous Buck PWM controller optimized f or high-perf ormance graphic microprocessors and supports the nVidia OVR2 specif ication with a PWM-VID interf ace.

The IC integrates a Constant-On-Time (COT) PWM controller, two MOSFET drivers with internal bootstrap diodes, as well as channel current balance and protection f unctions, including overvoltage protection (OVP), undervoltage protection (UVP), current limit, and thermal shutdown, all within a WQFN-20L 3x3 package.

The RT8816A adopts an RDS(ON) current sensing technique f or current limit, which is accomplished through continuous inductor current sensing, while RDS(ON) current sensing is used f or accurate channel current balance.

Overview

RT8816A Dual-Phase PWM Controller with PWM-VID Reference 1 General.

Key Features

of the RT8816A include an external ref erence input and PWM-VID dynamic output voltage control, where the f eedback voltage is regulated to track an external input ref erence voltage. Other f eatures include an adjustable switching f requency, dynamic phase number control, internal sof t start, power good indicator, and enable f unctions. The recommended junction temperature range is.
10C to 105C. 2 Features.
