NCL30080

Quasi-Resonant Primary

Side Current-Mode

Controller for LED Lighting

The NCL30080 is a PWM current mode controller targeting isolated

flyback and non−isolated constant current topologies. The controller

operates in a quasi−resonant mode to provide high efficiency. Thanks

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 secondary side feedback circuitry, biasing and an optocoupler.

The device is highly integrated with a minimum number of external

components. A wide V 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
