  • Description

    The MC33261P is an electronic component model, specifically designed for use as a preconverter in electronic ballast and in off−line power converter applications. It is an active power factor controller that features an internal startup timer, a one quadrant multiplier for near unity power factor, and a zero current detector to ensure critical conduction operation. The MC33261P also includes a high gain error amplifier, a trimmed internal bandgap reference, a current sensing comparator, and a totem pole output ideally suited for driving a power MOSFET. This model is available in both dual−in−line and surface mount plastic packages.
