    [SOLVED] Current source for high current LED driver- 24Vdc/max:16A

    Thanks guys. Good information. With this information at hand, I will make another few test and ask an external electrical engineer to design me the actual and final pcb, with the power supply, filters etc. You are the best.:wink:

    [SOLVED] Current source for high current LED driver- 24Vdc/max:16A

    I will have a look at it. Vishay WSK Serieshttps://www.mouser.es/new/vishay/vishay-dale-current-sensing-resistors/( Kelvin Sensing). I know, I came with the simplest circuit and left it there. I am not a electrical engineer but I can understand all that you have told me and it has been very...

    [SOLVED] Current source for high current LED driver- 24Vdc/max:16A

    What about "The low-side resistor adds undesirable extraneous resistance in the ground path"? Actually, during the test I carried out on the circuit, I have seen in my scope that for a duty cycle of 100msec, the differences between voltage peaks are 330uV at maximun. I going to sustitute the...

    [SOLVED] Current source for high current LED driver- 24Vdc/max:16A

    Hi, I have read this article from maxim: https://www.maximintegrated.com/en/app-notes/index.mvp/id/746 Apparently using a high-side configuration is better because. "The low-side resistor adds undesirable extraneous resistance in the ground path" and "an accidental connection that bypasses the...

    [SOLVED] Current source for high current LED driver- 24Vdc/max:16A

    I am working on designing a current source for a LED driver, which can work up to max:16A, as long as the driver stays on less than 500msec. Actually, the leds circutry is a Dome-light which is divided in 4 sectors. The 4 sectors have a common ground and they are trigger in PNP mode(24Vdc)...
