RT8811C Overview
The RT8811C is a 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...
