Evaluation Board | NCP1013LEDGEVB

The controller used in this application is a low cost monolithic design, the NCP1013. This, and the other members of the family, from the NCP1010 to the NCP1014, allow for the design of low cost, yet fully featured, switched mode power supplies. The design comprises an input filter, bridge rectifier, bulk capacitors and a line inductor, the power stage, rectifier diode and smoothing capacitors. Feedback is CVCC, constant current drive for the LED's with a constant voltage in the event of an open circuit output.
