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.

SILICON MONOLITHIC

INTEGRATED CIRCUIT

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.
