® RT8811C Dual-Phase COT Buck PWM Controller with Dynamic Voltage Control General Description The RT8811C 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 RT8811C adopts RDS(ON) current sensing technique. Current limit is accomplished through continuous inductorcurrent-sense, while RDS(ON) current sensing is used for accurate channel current balance.
