SSL5031CDB1210：Universal mains 18W Fixtures, non-isolated low-THD Buck LED driver demo board

The SSL5031CTS is part of a new range of LED driver ICs for non–isolated, non-dimmable LED solutions. The SSL5031CDB1210 demo board is a low THD, compact and low cost fixture solution using Buck topology. The SSL5031CDB1210 demo board drives a constant current through the LEDs from a rectified 90 - 265 VAC mains input voltage. This 18 W demo board is optimized for a LED string voltage of 53 V at 300 mA. The PCB design and the components used ensure that the board fits into fixture solutions and PAR/BR lamp shapes.
