LED Driver ICs Forum Discussions
Hello Team,
We are using TLD2131-3EP IC in our design. As mentioned in the datasheet
But we could see other terminology for K i.e., KLTx and KALLx
Could please explain what are these two terminology and where it is used.
Also how to calculated K value.
Regards

Hi,
Is there any Excel design tool for XDPL8219? I'm talking about a tool that can give us component information when we enter values such as Vout, Iout, Vin.
If you have, can you share it?
Thank you

Hello,
I am developing a 300W LED Driver 90V 3.25A.
Facing issue with following things
1. output voltage range requirement is 50-90V, currently it is 78-90V.
2. Output current keeps increasing after the load in CC mode like current starts from 3.15A and rises to 3.45A
3. while doing pilot lot many drivers found not working. IC is not getting start.

Show LessHi,
Good day.
We are third party programmer manufacturer.
Customer requires TLD1314EL for programming, and we need the programming guide for development.
Could you help to provide the programming guide to us for development?
Thank you.

Show LessI need to drive 2 types of leds with ILD8150
1. First LED was 20Vdc operating 7W LED.
And
2. Led 12W, 40Vdc
Please suggest the circuit for above two LEDs.
Dimming facility is not required.
Show LessI want to power a lamp with usb c (5V 2A).
Do I need to adjust the input voltage to power a LED (2,7V 65mA), or can I just power the IC with the provided 5V from the USB-C?

Hello. In the "Application note - Ballast IC Design for 54W UV-C Disinfection Lamp" on the Top and Bottom Views of the Demo Board one can spot component places for a presumably dc input? Silkscreened as 1-10V for a connector of sorts then traces towards what looks like a choke/transformer. These components I am referring to are all in the general area of the ac input. Can I ask for the purpose and perhaps the missing schematic?
Is that an alternative power source or an auxiliary regulated output for something?
