Product Summary

The MC33260P 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. The MC33260P is also optimized to offer extremely compact and cost effective PFC solutions. While it requires a minimum number of external components, the MC33260P 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.
