NCL30083 Dimmable Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting with Thermal Fold-back The NCL30083 is a PWM current mode controller targeting isolated www.onsemi.com flyback and non isolated constant current topologies. The controller operates in a quasi resonant mode to provide high efficiency. Thanks 8 8 to a novel control method, the device is able to precisely regulate a constant LED current from the primary side. This removes the need for s.
