SSL2109ADB1105：120V 18W PAR38 high PF Isolated LED driver demo board

The SSL2109AT is a high-efficient LED current controller IC for non-dimmable LED lamps. It controls a constant current through the LEDs from a rectified mains input voltage. The 18W SSL2109ADB1105 demo board is an isolated fly back configuration designed for driving typically a 10-LED string load from a 120V AC mains. The PCB dimension is compatible for both PAR38 and PAR30 form factors used in SSL applications. The demo board provides a simple and effective solution having a high power factor and a low THD.
