General Description

The RT8816B is a 2/1 phase synchronous Buck PWM controller which is optimized for high performance graphic microprocessor and computer applications.

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 functions including Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), current limit, and thermal shutdown into the WQFN-20L 3x3 package.

The RT8816B adopts RDS(ON) current sensing technique.

Overview

® RT8816B Dual-Phase PWM Controller with PWM-VID Reference General.

Key Features

external reference input and PWMVID dynamic output voltage control, in which the feedback voltage is regulated and tracks external input reference voltage. Other features include adjustable switching frequency, dynamic phase number control, internal softstart, power good indicator, and enable functions.
