General description

The SSL2101 is a Switched Mode Power Supply (SMPS) driver 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 high-voltage power switch, a circuit to allow

start-up directly from the rectified mains voltage and a high-voltage circuitry to supply the

phase cut dimmer.

For dimmer applications, an integrated dedicated circuitry optimizes the dimming curve.

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

– Use external bleeder transistors to provide extended dimmer interoperability
