Beschreibung
The NCL30488 [1] is a power factor corrected controller with primary side constant voltage (CV) and constant current (CC) control suitable for flyback, buck−boost or SEPIC converters. The NCL30488 is housed in an SOIC 8 package and targets high−performance LED drivers. These controller integrate a proprietary circuit for power factor correction and constant current control allowing to achieve a power factor above 0.9 and total harmonic distortion below 10% for universal mains input. This controller is normally primary side regulated, but the version (TBD) is compatible with secondary side regulation. In this version, the COMP pin features a pullup resistor to the internal reference voltage rail and allows directly connecting an optocoupler collector to the pin. The current−mode, quasi−resonant architecture of this controller optimizes the efficiency by turning on the MOSFET when the drain−source voltage is minimal (valley). The valley lockout and frequency foldback circuitry maintain high−efficiency performance in in light load during constant−voltage regulation.
