This digitally controlled boost converter makes driving high power LEDs from a 12 volt source really easy. But it has a really slow voltage rise time, so the LED takes 10 seconds or so to brighten up. NOTE: Also see Jim Conner's tests which highlight some potentially problematic bugs in this unit:

Hi Julian Ilett, thanks for that great video!
First of all, I am a little bit newbie about that type of device. I have exactly the same boost converter. I got it in a grab pack by chance. I search the Internet to get more information on it and then I found that video. I plan to use it for different applications/projects while prototyping/learning.
Now I have a few questions:
1) What is the range of voltage/current I can get out of it if I plug on its input a power adapter which has an output of DC 9V/500mA?
2) Is it possible, from that input source precicely (9V/500mA), to increase BOTH the input voltage and current, to get an output of let's say 40V/0.7A (like on the video) or more?
3) Is it possible as well, conversely, to reduce BOTH to output only, like 5V/100mA or anything else?
4) I read in the video description that the output current is 10A max and 400W max power. So I guess that if I want to output let's say 50V, I will max out at 8A of current (50V * 8A = 400W). But, is it true regarless the power adapter I plug in its input (keeping it within the input tolerance of 6V-40V/15A)? This is only theorically, to learn, I don't have that need, at least right now.
Thanks
Jonathan
i had a DC to DC Boost Converter like the one on the left. lower it as far as it can go., step up the amps. after put a load a on it. voltage dropped to 6vdc from 16vdc. then it sky rocketed the voltage on its own to 30vdc.
Don't know if you are answer this question but I wanted to run a string of LED lights when you get to the end you have exhausted your 12 volts down to 9 volts and some change, I wanted to use that to put into one of these units but the ones I've used that were very cheap seem not to be able to constantly run they turn off and on don't know why because when you put it on your voltage box it runs perfectly so all my tests doesn't work in the real thing I was trying to find something they can take something like LED lights boost it back up to the 12 volts from the nine volts and it seems to be blinking off and on can you take one of these modules and test LED lights is it feeding back what's happening I don't really care how long it takes it to reach up long as the current is constant so I can run all the LED lights on one single input.
What is the lowest current or amps you can put through that device
i think the rise in voltage is likely the micro stopping increments, reading current and voltage and then starting increments again, repeating this until it gets to the regulated values. Not a fast processor but also, safer to start lower and raise it, measuring and then allowing more current/voltage
Thanks for the video! you got a point on the speed of each type of unit: I didn't pay attention until I saw your video! 🙂
just to let you know that I have been "unsubscribed" from your channel automagically!!!!
subscribed back again.
can this run on 50 volts dc input?
hi,
Does meanwell 48v 1000w inverter runs..I can use this converter instead of 4 batteries…
Input 12volt / 48volt output…
Does it work smoothly. Can I use inverter.. thank you
Perhaps the designed did it that way to give it a rather crude "soft start".
LED Chip 500 Watt, 7A, 72 volt.
