NCL30030B3DR2G ON Semiconductor

NCL30030xy AWLYWWG 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 quasiresonant 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 SOIC16 NB MISSING PIN 2 achieve low harmonic distortion and nearunity power factor while CASE 751DT operating in a Critical Conduction Mode (CrM). The circuit incorporates all the features necessary for building a robust and MARKING DIAGRAM compact PFC stage while minimizing the number of external 116 components. BO/HV PFB The quasiresonant currentmode flyback stage features a GND MULT PCS/PZCD proprietary valleylockout circuitry, ensuring stable valley switching. th PControl PDRV This system works down to the 4 valley and toggles to a frequency PONOFF QDRV th foldback mode with a minimum frequency clamp beyond the 4 QCT QCS valley to eliminate audible noise. Skip mode operation allows Fault VCC excellent efficiency in light load conditions while consuming very low QFB QZCD standby power consumption.
