This document describes how to design a mains dimmable LED driver using the NXP SSL2101 LED driver IC in flyback mode. It includes a description of how mains dimmer compatibility is achieved.

Key enablers driving the expansion of LED lighting are the availability of high brightness LEDs and intelligent LED controllers. Product designers incorporating high brightness LEDs face many challenges. Among them are thermal management, driver scheme/topology and existing infrastructure.

To replace an existing dimmable incandescent or halogen light source, an electronic lamp driver system must be implemented that can operate with the existing dimmer switch while replicating the dimming behaviour of the existing light source. The NXP SSL2101 IC provides this functionality and, in addition, is a power converter. It combines these capabilities, enabling the lamp/module designer to integrate electronics in a cost- and size-effective way, whilst benefitting from optimal thermal trade-off, says NCP.
