onsemi | NCL30001DR2G

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.

The NCL30001 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.
