General description

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.

– control of an external power switch to allow the IC to provide any power

– control of external bleeder transistors to provide extended dimmer interoperability

The device includes a circuit that allows start-up directly from the rectified mains voltage.
