The RT8812C 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-20L 3x3 package.
The RT8812C 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. Using the method of
current sampling utilizes the best advantages of each
technique.资料下载
