MC33261 Datasheet Power Factor Controllers

Manufacturer: onsemi

Overview: www.DataSheet4U.com MC34261, MC33261 Power Factor Controllers The MC34261/MC33261 are active power factor controllers specifically designed for use as a preconverter in electronic ballast and in off−line power converter applications. These integrated circuits feature an internal startup timer, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical conduction operation, high gain error amplifier, trimmed internal bandgap reference, current sensing comparator, and a totem pole output ideally suited for driving a power MOSFET.
