MC33232 Power Factor Controller The MC33232 is the monolithic Integrated Circuit using the SMARTMOS® process as the new technology. And is active power factor controller specially design for use as off−line power converter application. This integrated circuit features an internal startup timer for stand−alone application, a one quadrant multiplier for near unity power factor, zero current detector to ensure critical condition operation, transconductance error amplifier, quickstart circuit for enhanced startup, trimmed internal bandgap reference, current sensing comparator, a totem pole output ideally suited for drive a power MOSFET, and a one shot−rigger circuit to eliminate a problem at the light loading. Also included are protective features consisting of an overvoltage comparator to eliminate runaway output voltage due to removal, and a protect circuit to eliminate thermal runaway. This device is available in dual−in−line and surface mount plastic package.
