The NCL30083 is a PWM current mode controller targeting isolatedflyback and non−isolated constant current topologies. The controlleroperates in a quasi−resonant mode to provide high efficiency. Thanksto a novel control method, the device is able to precisely regulate aconstant LED current from the primary side. This removes the needfor secondary side feedback circuitry, biasing and an optocoupler.The device is highly integrated with a minimum number of externalcomponents. A robust suite of safety protection is built in to simplifythe design. This device is specifically intended for very compact spaceefficient designs. It supports step dimming by monitoring the AC lineand detecting when the line has been toggled on−off−on by the user toreduce the light intensity in 5 steps down to 5% dimming.
