Description

The SSL5511T is a high-efficient analog/PWM dimmable controller IC for LED solutions. The SSL5511DB1234 demo board is a compact and low cost 36 W single stage flyback LED driver solution optimized for high power factor and low THD operation with a 0-10 V analog dimming interface or PWM dimming..

The SSL5511DB1234 demo board drives a constant current through the LEDs from a rectified universal mains input voltage. This 36 W demo board is optimized for a LED string voltage of 48 V at 705 mA. The design and the components used are optimized for various fixture applications.
