Overview
SSL2101 SMPS IC for dimmable LED lighting Rev.
04 — 28 August 2009 Product data sheet 1.
General description The SSL2101 is a Switched Mode Power Supply (SMPS) controller IC that operates in combination with a phase cut dimmer directly from rectified mains.
It is designed to drive LED devices.
The device includes a high-voltage power switch and a circuit to allow start-up directly from the rectified mains voltage.
Furthermore the device includes high-voltage circuitry to supply the phase cut dimmer.
For dimmer applications, integrated dedicated circuitry optimizes the dimming curve.
