SSL5231DB1242：230V 4W dual Candle, mains dimmable non-isolated Buck-boost LED driver demo board

The SSL5231T is part of a new range of LED driver ICs for non–isolated, mains dimmable LED solutions. The SSL5231DB1242 demo board is a low THD, compact and low cost Candle shaped solution using Buck-boost topology. The SSL5231DB1242 demo board drives a constant current through the LEDs from a rectified 230 VAC mains input voltage. This dual 4 W demo board is optimized for a LED string voltage of 90 V at 2 x 37 mA. The design and the components used ensure that the board fits into a Candle lamp base.
