NCL30080BSNT1G.

The NCL30080BSNT1G is a Quasi-resonant primary side Current-mode Controller for LED lighting. It is targeting isolated fly back and non-isolated constant current topologies. This device is able to precisely regulate a constant LED current from the primary side. This removes the need for secondary side feedback circuitry, biasing and an optocoupler. The device is highly integrated with a minimum number of external components. A wide VCC range simplifies the design process and allows a single design to support a wide LED forward voltage range. A robust suite of safety protection is built in to simplify the design. This device is specifically intended for very compact space efficient designs.
