Datasheet Summary
Dual-Phase PWM Controller with PWM-VID Reference
1 General 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 protection (UVP), current limit, and thermal shutdown, all within a WQFN-20L 3x3 package.
The RT8816A adopts an RDS(ON) current sensing technique f or current limit, which is acplished through...
