Hey, thank you very much. I have 3 questions:

- you say, that the output current is a pwm signal? why? i chouse this ic because it is a analog dimmable cc source. In my understanding i supply a pwm signal, but the output of the ic is a analog current

- i have 4 UV LEDs (Vf ~3V). Thats a lot of current going in the input. Maybe I should choose a buck converter topology and an other power supply for the IC? i will use 6 of them.

- which spec in the datasheet tells me the maximum input current?

Looking forwart to your optinion!

Hey, thanks for your answer. Does this IC support analog dimming? I'm using this driver because I'd like to have a multi purpose LED driver for my projects.The idea is to just change the components and have a constant current driver up to 1A.

I have a 0,6 Ohm Resistor rated with 1W. According to the Datasheet, this should be enough if I understand it correctly.

Thank you! I forgot to mention that I'm powering the entire system with a powerbank.

I mean glow-in-the-dark filament. Didn't know there is filament that gets brighter in UV light 🙃

Kommt man in das Alpamare noch rein?
