NCL30088 Datasheet, PDF (1/26 Pages) ON Semiconductor – Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller

NCL30088
Power Factor Corrected
Quasi-Resonant Primary
Side Current-Mode
Controller for LED Lighting
with Thermal Foldback
The NCL30088 is a power factor corrected flyback controller
targeting isolated and non−isolated constant current LED drivers. The
controller operates in a quasi−resonant mode to provide optimal
efficiency. Thanks to a novel control method, the device is able to
tightly 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 robust suite of safety protection is built in to simplify
the design. This device is specifically intended for very compact,
space efficient designs.
