LM3445: TRIAC dimmable wall light UK-US-EU

Sander Van Driessche

Part Number: LM3445

Good day,

I need to design a TRIAC dimmable device with 10 LEDs (3.2V @ 20mA). I was thinking of using the LM3445 since this seems to be a good option.

The requirements of the end product are:

compatible with UK-US-EU mains (90 - 260 VAC, 50 - 60 Hz)
compatible with most phase dimmers
safe
small - light will be fixed in wall socket

Is the LM3445 a good option or would it be better to search for an alternative?

Thank you for the support.

Hi Customer,

Do you need an isolated output? Do you need PFC?

Hi Steven,

Isolated output is not really an option since the product cannot fit a transformer, and also not really necessary. PFC would be a plus but it is not a strict requirement.

Thank you,

Sander
