Advanced LED Driver Circuit Design - Circuit Tips and Tricks
One of the first projects that aspiring electronic designers or engineers undertake is making an LED blink. Completing this task with a simple resistor to limit the current is relatively simple. Many people then believe that this is the standard “end-all, be-all” for LED control. Many applications call for a different approach. In this video, I outline a few common alternative strategies and some unorthodox methods that we have used in the past for LED driver circuits.

Hi, I am currently studying microelectronics at university and i have to say that the amount of useful information in your videos are beyond university lessons. Thanks a lot and dont give up your videos are awesome

The thing about dimming LEDs with current is that I believe the light spectrum can vary a lot when the current changes - with PWM it should stay much more consistent especially at lower luminosity. Also, if using LED strips, I believe PWM is the only practical way to vary the light, because the way they are constructed

Honestly, not sure about which affects the linearity more (PWM vs CC). I do know that if the exact brightness is important, it's critical to calibrate it and use a lookup table or algorithm to control it.

Thanks for the insights. Your videos are very knowledgeable. Very practical oriented instead of only theoritical(not useful).

I totally subscribed to Your channel. They're right ▶️ don't You ever give up man. I'm 34 and God damn I stand no chance to ever be this clever. I will tell about that channel to my friends interested in electronics.

Hi this is a nice video. I wonder if there is source schematic file provided? A lot of contents in ur videos but they are too small to be seen

Hi, thanks for the very informative video! What are some pointers when it comes to UL certification?

Excellent video Kyle. when working on LED drivers for your projects, do you take into consideration the flux and voltage binning of the LEDs as well as color wavelengths? Thank you.

@MicroTypeEngineering 3 жыл бұрын

Oh boy, that's a question! So yes, they absolutely matter. Every project I've been on like this, the client will spec them for us. Since we don't have any LED flux testers, I don't know that process too well. But typically you can only bin 2 out of the 3 specs. So you'll want to use a constant current driver rather than relying on a fixed forward voltage

@phantomhck 2 жыл бұрын

Commonly the light engines will have binning resistors to adjust current as well as thermal fold back NTCs. Many drivers have an analog range for the dim/PWM pin usually around 0.5v-2.5v. a voltage divider can then be as simple as a 100k ntc on the bottom to ground and a current adjust resistor on the top. That's all separate from the main current sense resistor.

hi, please revert back ASAP since its very imp for me to know. I am using 3x10 cob led along with cc driver that is 960mA,30-35v and the connection type is series-parallel, now the issue is if one of my string fails so will it add up to the remaining LED or no??? I made some calculations too: 1 led = 30/10 = 3V 1 led current rating = 960mA/10 = 96mA so single led is taking 3v and 96mA for 1 string: 3x10= 30V, 96x10= 960mA this is for 1 string, i am extremely confused if the CC driver rating is only for one string or what please help i don't want it to override other strings.
