Onsemi NCL30000LED3

Beschreibung

This is a single stage power factor corrected isolated flyback LED driver intended for lighting applications such as down lights, PAR lamps and residential/commercial indoor and outdoor LED fixtures. The NCL30000 is based on a fixed on-time, critical conduction mode (CrM) flyback topology. The board is designed to provide 350 mA of constant current and drive up to 15 W of LEDs in a single string. Closed loop regulation of the LED current is achieved which results in accurate current regulation across a range of LEDs forward voltage and line conditions.The design is power factor corrected with a nominal PF of >0.96. The design supports an input range of 90-305 Vac which include the US commercial lighting voltage of 277 Vac. Unlike the other two reference designs in this series, this version of the board is designed for static lighting applications that do not require line dimming
