Combination Power Factor
Correction and
Quasi-Resonant Flyback
Controllers for LED Lighting
This combination IC integrates power factor correction (PFC) and
quasiâresonant 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 nearâunity 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.
The quasiâresonant currentâmode flyback stage features a
proprietary valleyâlockout circuitry, ensuring stable valley switching.
This system works down to the 4th valley and toggles to a frequency
foldback mode with a minimum frequency clamp beyond the 4th
valley to eliminate audible noise. Skip mode operation allows
excellent efficiency in light load conditions while consuming very low
standby power consumption.
