MC33260 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 synchronized and in any case, it features very effective protections that 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.
