We see from your search that you're looking for information on the term "PFC",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Gate driver IC resists negative voltage from
International Rectifier, which we summarised at the time by saying "International Rectifier's IRS26302D incorporates negative voltage immunity circuitry to protect the system from catastrophic events such as high-current switching and short-circuit
conditions".
Earlier in the week,
we featured the news release Power component deal covers UK and Ireland from
Europower Components: "Acting as an extension of EPCOS' sales and technical team, Europower Components will be offering highly focused technical support in the UK and Ireland".
In January 2008, we covered the news from STMicroelectronics
concerning its L6566 selectable multimode controller
- take a look at Dual operating modes boost controller flexibility
which says: "The L6566 selectable multimode controller is suitable for applications such as flyback AC/DC adapters, TV and LCD monitors, small size LCD TVs, high end chargers and other consumer equipment".
Take a look also at the news release from Vicor UK, Low-profile switcher boosts power density,
as well as Supplies squeeze 275W into 1U from Power Sources Unlimited,
and Power factor conditioner copes with more power from Texas Instruments (April 2006-).
