Let’s discuss the details.

For different combinations of current and LEDs there are a few things that need to be computed which you can find about in the data sheet: It takes 4 bytes: So, the optimum value of the inductor needs to be optimized. However I was able to find only the first 4.

Here are lef few photos and video of the driver: I can also provide the prototyp More. The email address is already associated with a Freelancer account.

Texas Instruments LM3409HVEVAL/NOPB, LED Driver Evaluation Board for LM3409HV

For additional understanding see section 2. Apply lm309hv similar jobs. For analog dimming, all components are required and the outer two pairs of pins need to be shorted on the 4 pin header.

In your case the input voltage 42V and output load LED’s are fixed.
