General Description

The RT8817A 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-24L 4x4 package.

The RT8817A adopts RDS(ON) current sensing technique.

Overview

® RT8817A 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, internal soft-start, power good indicator, and enable functions. Ordering Information RT8817A Package Type QW : WQFN-24L 4x4 (W-Type) (Exposed Pad-Option 1) Lead Plating System G : Green (Halogen Free and Pb Free) Note : Richtek products are :  RoHS compliant and compatible with the curr.
