RT8811B, Dual-Phase COT Buck PWM Controller

® RT8811B Dual-Phase COT Buck PWM Controller with Dynamic Voltage Control General .
The RT8811B 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

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
