ONSEMI NCP1622DCCSNT1G Power Factor Controller
The NCP1622 is an enhanced, high-efficiency power factor controller designed for PFC boost stages in industrial and commercial power supplies. It features Valley Synchronized Frequency Fold-back (VSFF) operation, automatically transitioning between Critical Conduction Mode (CrM) and Discontinuous Conduction Mode (DCM) to maximize efficiency across load ranges. Capable of operating in SKIP mode at very low loads on certain versions, it reduces stand-by losses and maintains near-unity power factor. The device includes overcurrent, overvoltage, thermal shutdown, brown-out detection, and zero current detection features, housed in a compact TSOP-6 package, suitable for non-latching, high-reliability power stage applications.
