NettetThe NCL30088 is an Ac-Dc power factor corrected flyback controller targeting isolated and non−isolated buck-boost/SEPIC constant current LED drivers. The controller operates in a quasi−resonant mode to provide optimal efficiency. Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side. Nettettwo-string LED driver are provided to verify the studied results. Introduction: In ac–dc power converter applications such as multiple-string LED driver for street lighting [1], power factor correction (PFC) is usually required to meet input current harmonic standard of IEC61000-3-2 Class C [2]. In addition, current sharing of multiple- NettetLED Driver (Constant Current), LA Series Features: - Constant current mode - Installation: Independent - Universal AC input / full range (100 – 240 Vac) - Fully encapsulated with IP67 - Protections: Short circuit / over current - UL 1310 Class II power unit, pass LPS - Small and compact size - 100% full load burn-in test asp datagrid ajax
