SSL2102T/DB/FLYB120V: 0.4 ~ 1.05A @ 9 ~ 23V, 85 ~ 276VAC

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.

The board needs to be connected to mains voltage. Touching the reference board during operation must be avoided at all times. An isolated housing is obligatory when used in uncontrolled, non-laboratory environments. Even though the secondary circuit with LED connection has a galvanic isolation, this isolation is not according to any regulated norm. Galvanic isolation of the mains phase using a variable transformer is always recommended.
