Overview of NCL37733BSNT1G

The NCL37733 is a compact driver for power−factor corrected flyback and non−isolated buck−boost and SEPIC converters. The controller operates in a quasi−resonant mode to provide optimal efficiency, and embeds a proprietary control method which allows theLED current to be tightly regulated from the primary side, thus eliminating the need for a secondary−side feedback circuitry and for an optocoupler.
