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
SSL2102主要特性:
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.
SSL2102應用:
The SSL2102 is suitable for high efficiency and high power factor SSL applications below 25 W, these include:
SSL retro-fit lamps (e.g. GU10, E27) from 8 W to 15 W.
LED modules, separate power supplies, e.g. LED spots, down-lights from 15 W to 25 W
LED strings, e.g. retail display up to a maximum of 25 W

SSL2102 19 W - 22 W LED驅動器
The SSL2102 19 W to 22 W LED driver is a solution for a professional application with multiple high power LEDs that requires galvanic isolation and a safe output voltage. It is mains dimmable for both forward phase (triac) dimmers, and reverse phase (transistor)dimmers. It can generate up to 22 W output power, which is equal to a 150 W incandescent lamp (at 63 Lumen/W). Examples are shelf lighting, down lighting, LED lighting for bathrooms etc. The design gives an example of how to make a driver that is suitable for small form factor applications such as retrofit lamps.
