Why independently?each one of them requires independent PWM
Why independently?
and .. why no specifications? It makes a big difference whether you are looking for 16 bit 10 MHz PWM or 8 bit 1kHz PWM.
Also power supply, signal voltage levels, interface...
I did a quick internet search for "channel pwm generator ic" and immediately found LT8500.
Is this similar to what you are looking for?
Why independently?
is there any IC that has couple of independent PWM channels and I can program
it using any interface ?
Hello !
I have 24 high power LED drivers and each one of them requires independent PWM, is there any IC that has couple of independent PWM channels and I can program it using any interface ?
I asked, because the OP states that the LED drivers need independent PWM...Why independently?
I was also thinking how to find more elements like LT8500 because when I check the LED drivers they usually are constant current and not PWM output or they are constant current (sink) with PWM. But I was looking for only PWM output and not current sink IC / constant current output.
The LT8500 is kinda okey with that, it is PWM without constant current (sink). But usually I just find drivers with constant current and max 3 PWM.
Dana I see what you've showed me but I don't know what PSoC is neither I don't know how to use it or how it looks like. I was trying to find a specific IC because they are specialized in this particular thing.
This PSoC is similar to Logisim I used sometimes or FPGA using premade blocks.
I was looking just for PWM generator nothing more ;> Because I couldn't find anything just LED drivers so far but LT8500 is a good idea but wanted to know how to find more propositions to choose.

So I understand it´s not the requirement by the LED driver to get independent PWM, but it´s the OP´s requirement to drive them independently.
I´m back when there are useful specifications. I just see a lot of riddles in text.
Microcontrollers can do soft_PWM ... it just depends on the PWM requirements asked in post#2.
You seem to neither read posts nor datasheets.
So the unknown LEDs are distributed on long wires with some independent light sensors unaffected by LEDs on long cables driven by a central PWM and current limiter.
I can imagine there will be many challenges with this concept.
In post#2 I asked forThanks I guess I'll try again on my own.
While a PWM is defined by frequency, signal levels, duty cycle.I don't know what the PWM has to be
Another option is the TLC5947 from Texas Instruments. It's a 24-channel PWM driver with a serial interface, allowing for independent control of each channel. You can program it using a variety of microcontrollers and interfaces.Hello !

It took you 14 posts to eventually say what LED driver you use. ... that is the very information for frequency, signal levels, duty cycle .. asked in post#2
In post#2 I asked for
*supply, signal voltage levels, interface...
--> did you answer the question?
In post#2 I told you about LT8500. I also asked:
* Is this similar to what you are looking for?
--> I still don´t know whether you find it suitable, and if not, why?
While a PWM is defined by frequency, signal levels, duty cycle.
