RT8813D Datasheet | Richtek

® Multi-Phase PWM Controller with PWM-VID Reference General Description The RT8813D is a 3/2/1 phase synchronous Buck PWM controller which is optimized for high performance graphic microprocessor and puter 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 RT8813D adopts RDS(ON) current sensing technique. Current limit is acplished through continuous inductorcurrent-sense, while RDS(ON) current sensing...
