Product Summary

The MC33262PG is a active power factor controller specifically designed for use as a preconverter in electronic ballast and in off-line power converter applications. The MC33262PG features an internal startup timer for stand-applications, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical conduction operation, transconductance error amplifier, quickstart circuit for enhanced startup, trimmed internal bandgap reference, current sensing comparator, and a totem pole output ideally suited for driving a power MOSFET.
