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 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
