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 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 V_CC 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.
