Power Factor Controller
The MC33232 is the monolithic Integrated Circuit using the
SMARTMOS
?/DIV>
process as the new technology. And is active power
factor controller specially design for use as offline power converter
application. This integrated circuit features an internal startup timer
for standalone 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 shotrigger 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 dualinline and surface mount plastic package.
