NCL30030 - Combination Power Factor Correction and Quasi-Resonant Flyback Controllers

Pin Out Name Function 1 BO/HV Performs input brown *out detection and line voltage range detection. 2 Removed for creepage distance. 3 MULT This is the output of the multiplication of the BO and Control signals. A capacitor should be put on this pin for filtering. Suggested values .

NCL30030 Combination Power Factor Correction and Quasi-Resonant Flyback Controllers for LED Lighting This combination IC integrates power factor correction (PFC) and quasi resonant flyback functionality necessary to implement a compact and highly efficient LED driver for high performance LED lighting applications. The PFC stage utilizes a proprietary multiplier architecture to achieve low harmonic distortion and near unity power factor while operating in a Critical Conduction M.

NCL30030 Features

* necessary for building a robust and compact PFC stage while minimizing the number of external components. The quasi

* resonant current

* mode flyback stage features a proprietary valley

* lockout circuitry, ensuring stable valley switching. This system works down to the 4th valley
