SSL2101T/DB/FBCB120V: TRIAC Dimming, 0.4 ~ 0.8A

Summary

The SSL2101 12 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 16 W output power, which is equal to a 100 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 drive that is suitable for small form factor applications like retrofit lamps.

the board is designed to work with multiple high power LEDs with a total working voltage of between 9 V and 23 V. The output current can be limited using trimmer R20.
