SSL2103 is a Switched Mode Power Supply (SMPS) controller IC designed for LEDlighTIng applicaTIons. It is an extension of the NXP SSL2101/SSL2102 product platform,allowing easy design of derivaTIve applicaTIons.When used in combination with a phase cut dimmer connected directly to a rectifiedmains, it provides dimmability to the application.In dimmer applications, integrated dedicated circuitry optimizes the dimming curve.• SSL2101: fully integrated LED driver for lamps up to 10 W• SSL2102: fully integrated LED driver for lamps up to 25 W• SSL2103: gives the application designer flexibility permitting the:– control of an external power switch to allow the IC to provide any power– control of external bleeder transistors to provide extended dimmer interoperabilityThe device includes a circuit that allows start-up directly from the rectified mains voltage.
