RT8816A Description
The RT8816A is a 2/1-phase synchronous Buck PWM controller optimized f or high-perf ormance graphic microprocessors and supports the nVidia OVR2 specif ication with a PWM-VID interf ace. 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 f unctions, including overvoltage protection (OVP), undervoltage...
