1 / 21 page  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 Easy migration to existing lighting control infrastructure, TRIAC and transistor dimmers I Supports majority of available dimming solutions I Valley switching efficiency is optimized by dedicated built-in circuitry I Built-in demagnetization detection I The IC has Over Temperature Protection (OTP) built-in I Short-Winding Protection (SWP) and Over Current Protection (OCP) I The IC has internal VCC generation that allows start-up from rectified mains voltage I Natural dimming curve by logarithmic correction I Limited external components required due to high integration level I 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 W I LED strings, e.g. retail display up to a maximum of 25 W For power ratings below 15 W (for LED modules) and 8 W (for SSL retrofit) NXP offers the SSL2101.
