NCL30488_V01規(guī)格書(shū)詳情
The NCL30488 is a power factor corrected flyback controller
targeting isolated constant current LED drivers. The controller
operates in a quasi?resonant mode to provide high 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, its biasing and for 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.
