If you need Zebralight, you can buy it.
I`m not sure boost-buck drivers have visible benefits with 1xli-ion, main advantages of them open when you are using 1-2 primary lithium cells.
Boost drivers use high frequency circuit engineering that is thousands times more tough to circuit layout design than fet or linears. If you`ll copy components while you don`t understand what are you doing - the only thing you can get is lots of problems with non (half) workable driver.
Components main values are not problem, they are simple to count with calculator.
Other important components characteristics that influence on driver work are known and you can choise components that will fit this requirements best.
Schematic circuit diagram is well known and can be used with no problems.
Layout design is much harder than everything posted upper. You can copy it, or use some literature how to make it better, but to make good driver we need a person that have learned and worked with high frequency circuit engineering (I haven`t).
Software is most mysterious thing for me. But all secrets are inside it.
theomajigga, from what I can see from the PCB picture, the voltage feedback is set around 6V, and the ILIM at around 10A on battery. Are you regulating the secondary current, or you rely on these 10A on the battery?
If you have any schematics available, I will be glad to take a look.
He hasn't been on in over 4 months, so who knows when/if he'll be back . These boost drivers have become common in commercial lights now, but still it would be fantastic to have an open source design so we can build and program our own.
This thread was one of the reasons I went ahead and began an engineering degree. Having a kid and COVID postponed things somewhat, but I’m now delving back into learning about electronics. It’s great being able to begin to understand what some of this is.
Hey all, sorry I never finished this went through a bad breakup, and honestly a lot of life was not very fulfilling anymore! Hobbies died off, and you all know, typical bs.
Since then, got married, and moved on to different things (cars, and cars, and restoring old trucks).
Sorry I never got back to any of you on this project.
The GBX20 is using the driver that I was using, really cool to see someone else caught on to the specs
The reason for the checkin, I was talking to a buddy about electronics, and I had mentioned to him that I was one of the first to make a single battery driver for XHP packaged drivers, so I came back to have a look!
Hope everyone is well, and I will probably never be back on here, unless I find something new to work on! If anyone want the gerber files (possibly outdated and too old to use anymore) or the BOM I will see what I can dig up!
