What value should I use for D? I would also need to be able to dim each color individually. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering.

Texas Instruments LM3406MHEVAL/NOPB, 1.5 A LED Driver Evaluation Board for LM3406

Driving W LEDs with lm Specifically for the inductor and capacitors. The product detailed below complies with the specifications published by RS Components. I would also need to be able to dim each color individually. For l3406 the LEDs I mounted them on aluminum blocks and those onto a stainless steel tube.

Thank you for your feedback. But if you learned how to read a datasheet it was worth it already: The LM please use capital letters is a switch mode current regulator. The Manufacturers reserve the right to change this Information at any time without notice.

What value should I use for D? Are there complete boards of the circuit available at a reasonable price?

It works for 6 months now, so I think it is not all that bad. Would I need to heatsink the LM’s if they get an input voltage of say 12, but are only outputting like 4. The simplicity is that there are always 3 LEDs in a row. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering.

Ok so I do need all the other components listed In my case km3406, is it dim pin is not necessary to connect anything?

So far my plan is to drive them with an lm with the LEDs in series strings of 4, which would mean I would need 5 lm ics.

I would like to preface this post with stating that I am pretty new to the world of electronics. If the psu is at 12 volts, and the string doesn’t dissipate the full 12 volts, would I need to add a resistor in line with the LEDs, or would throttling it down lef pwm be enough protection?

I have an changing input voltage.

Hi there, I wanted to have an LED illumination on my aquarium as well, but I wanted it low cost and simple. I find that that pin is left open in input voltage comparator for PWM dimming. The lm from what I understand would allow me to dim the LEDs hooked up to it with a pwm signal from the arduino; the voltage would be modified by the pwm signal and the current would be fixed.

Sorry, I think I am still confused. Home Questions Tags Users Unanswered. But you can get 4 levels of current with just 2 switches, by having the switches connect extra resistors ler parallel. What is high power Led actually. I would like to feed it into LM and have varying brightness from the Led.

The count is probably going to be something like 4 red, 4 green, 8 blue, and 4 white. Adding an external input diode and using the internal VINS comparator allows the LM family to sense and respond to dimming that is done by PWM of the input voltage.
