SSL2102

SSL2102 Mains LED driver IC for dimmable LED lighting Rev. 01 — 29 June 2009 Product data sheet 1. General description The SSL2102 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 direct start-up 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. 2. Features I I I I I I I I I I Easy migration to existing lighting control infrastructure, TRIAC and transistor dimmers Supports majority of available dimming solutions Valley switching efficiency is optimized by dedicated built-in circuitry Built-in demagnetization detection The IC has Over Temperature Protection (OTP) built-in Short-Winding Protection (SWP) and Over Current Protection (OCP) The IC has internal VCC generation that allows start-up from rectified mains voltage Natural dimming curve by logarithmic correction Limited external components required due to high integration level Thermal enhanced SO20 wide body package. 3. Applications The SSL2102 is suitable for high efficiency and high power factor SSL applications below 25 W, these include: I SSL retro-fit lamps (e.g. GU10, E27) from 8 W to 15 W. I LED modules, separate power supplies, e.g. LED spots, down-lights from 15 W to 25 ...
