SSL2103: Dimmable Greenchip controller for LED lighting

The SSL2103 is a Switched Mode Power Supply (SMPS) controller IC that operates in combination with a phase cut dimmer directly from the rectified mains. It is designed to drive LED devices. The device includes a circuit to allow direct start-up from the rectified mains voltage.

For dimmer applications, an 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 to:

Use an external power switch to allow the IC to provide any power

– Use an external bleeder transistors to provide extended dimmer interoperability

SSL2103主要特性和优势:

 Easy migration to existing lighting control infrastructure

 Supports most available dimming solutions..
