RT8811C, Dual-Phase COT Buck PWM Controller

® RT8811C Dual-Phase COT Buck PWM Controller with Dynamic Voltage Control General .
The RT8811C is a 2/1 phase synchronous Buck PWM controller which is optimized for high performance graphic microprocessor and computer applications.

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/external soft-start, power good indicator, and ena

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 4x
