Description
Power Factor Controller
Manufacturer
ONSEMI [ON Semiconductor]
Datasheet
MC33232
Power Factor Controller
SMARTMOS
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.
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.
