Stage Power Factor
Correction and Step-Down
Offline LED Driver
The NCL30001 is a highly integrated controller for implementing
power factor correction (PFC) and isolated step down ac−dc power
conversion in a single stage, resulting in a lower cost and reduced part
count solution. This controller is ideal for LED Driver power supplies
with power requirements between 40 W and 150 W. The single stage
is based on the flyback converter and it is designed to operate in
continuous conduction (CCM).
The NCL30001 can be configured as as constant current driver or a
fixed output driver for two stage LED lighting applications. In
addition, the controller features a proprietary Soft−Skip to reduce
acoustic noise at light loads. Other features found in the NCL30001
include a high voltage startup circuit, voltage feedforward, brown out
detector, internal overload timer, latch input and a high accuracy
multiplier. The multi−function latch off pin can also be used to
implement an overtemperature shutdown circuit.
