SSL5021BDB1267：230V 6W Candle, non-isolated low-ripple Buck LED driver demo board with Bipolar switch

The SSL5021BTS is part of a new range of LED driver ICs for non–isolated, non-dimmable LED solutions. The SSL5021BDB1267 demo board is a low ripple, compact and low cost Candle/GU10 shape solution using Buck topology and an ultra low cost Bipolar switch. The SSL5021BDB1267 demo board drives a constant current through the LEDs from a rectified 230 VAC mains input voltage. This 6 W demo board is optimized for a LED string voltage of 80 V at 71 mA. The single sided PCB design and the components used ensure that the board fits into an Candle and GU10 lamp base.
