Overview

® RT8817A Dual-Phase PWM Controller with PWM-VID Reference 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.
Current limit is accomplished through continuous inductorcurrent-sense, while RDS(ON) current sensing is u...
