DC1831A - EVAL BOARD LED DRIVER LT3763 - please supply "PCB Original Design File"

I just download the PADS .pcb file from the ADI website and the file seems to open o.k. - see the image below.  I exported the .pcb file to a .asc which I uploaded here.

Hi Sir,

Can i have the ADI website link so i will know how to download similar files in future.

Or can u teach me where to go for such PCB PADS files?

It's easy.  Just go to the LT3763 page on the ADI website.  Then scroll down to Evaluation Kits and under that you will see DC1831A and under that you will see Resources.  Then click on the DC1831A - Design Files link.   

Please use: https://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/dc1831a.html#eb-documentation

Download the Design Files.

Hi Sir,

I have a big problem.

How do i fully dim down the LED using DC1831A?

I supply 12vDC to power a LED at 0A to 10A.

I used CTRL1 port and supply it with 0v to 1.5v to dim down the LED but the LED is still dimly lighted up eventhough my CTRL1 is at 0vDC.

So how do i fully dim down my LED to zero light output?

Hi

To Zero out the LED current pull PWM pin voltage below 1.5V. On graph titled "Regulated Sense Voltage" of the data sheet, 0V on the CTRL 1 would still maintain a small sense voltage which would mean there is still current passing on the sense resistor which could turn on the LED 

Regards,
