NCL30030

Combination Power Factor

Correction and

Quasi-Resonant Flyback

Controllers for LED Lighting

www.onsemi.com

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 Mode (CrM). The circuit

incorporates all the features necessary for building a robust and

compact PFC stage while minimizing the number of external

components.

This system works down to the 4 valley and toggles to a frequency

foldback mode with a minimum frequency clamp beyond the 4

valley to eliminate audible noise. Skip mode operation allows

excellent efficiency in light load conditions while consuming very low

standby power consumption.
