SSL2103： SMPS controller IC for dimmable LED lighting

SSL2103 is a Switched Mode Power Supply (SMPS) controller IC designed for LED lighting 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 rectified mains, 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 interoperability
