GreenLinet Compact
Power Factor Controller:
Innovative Circuit for
Cost Effective Solutions
The  MC33260  is  a  controller  for  Power  Factor  Correction
preconverters  meeting  international  standard  requirements  in
electronic  ballast  and  off- -line  power  conversion  applications.
Designed to drive a free frequency discontinuous mode, it can also be
synchronizedandinanycase,itfeaturesveryeffectiveprotectionsthat
ensure a safe and reliable operation.
This circuit is also optimized to offer extremely compact and cost
effective PFC solutions. While it requires a minimum number of
external components, the MC33260 can control the follower boost
operation that is an innovative mode allowing a drastic size reduction
of both the inductor and the power switch. Ultimately, the solution
system cost is significantly lowered.
Also able to function in a traditional way (constant output voltage
regulation  level),  any  intermediary  solutions  can  be  easily
implemented. This flexibility makes it ideal to optimally cope with a
wide range of applications.
