Wight, are you talking about placing them manually or with the ULP?

With the ULP! For example, this will not result in anything other than the first via having a NAME of GND:

[RMM]

On mine it names all of them. I am still running 6.5.

Crap, heh. Thanks! If only the CHANGE tool could change NAME it wouldn’t be a big deal.

EDIT: I’m on 7.1 FWIW.

@wight

Has anyone else had trouble with keeping all the vias assigned to the same NET? When I used this to do a circle of GND vias the other day only my first via was assigned to GND. Maybe I’m forgetting something.

I have the same problem, also using 7.1. Maybe they fixed it in the new 7.2.

That occurred to me, so I updated to 7.2 a few hours ago. It made no difference.

Darn. I’ll fire away an email to them. Do the same, the more people that point it out the more likely it will get fixed in the next version. support@cadsoftusa.com or support@cadsoft.de.

Does anybody know where I can get some FET’s for the BLF DD boards?

The similar single FET at Digikey is out of stock………

[DB_Custom (Dale)]

Try Mouser.
You might check with Richard and/or Wight as to which ones can be used as alternates. There’s a few that’ll work as well or better. I’m not gonna say cause I’ll probably get it wrong.

[pilotdog68]

I believe this is the right one

[pilotdog68]

That’s for the original driver, not for wights single sided boards

[DB_Custom (Dale)]

That one works to replace the 70N02 but the newer drivers take a different footprint altogether so it depends on which driver you’re building.

There are lots of different ones that will work. What you are really looking for is a low gate charge and low on resistance at 4.5v, which gives some indication as to how it will perform in our applications with relatively low gate charges. I am using the IRFR3711ZTRPBF FET now.

Obviously buying in bulk from Mouser or Digikey will net you a better price than buying from me. If you are going to build a lot of drivers, that's what I'd recommend doing.

And here I was recommending AOD510 in another thread just today. Oh well. (I don’t think Mouser carries any AOD brand products.) I really don’t have any other DPAK sized FETs in mind, having switched to LFPAK56 & similar for my own designs. Pilotdog68’s suggestion of IRFR3711ZTRPBF is probably the best bet for those BLFxxDD drivers which use DPAK. RMM has them and they are also in stock at Mouser.

When you say newer drivers, you are talking ones like the single sided driver from wight, right?

RMM also has some in the pipeline: Post #3441. Other than his new drivers I think mine are the only ones currently using LFPAK56.

Offhand I say that it appears to be of slightly higher quality (plastic molding / PCB / soldering) than the bottom dollar ones.

EDIT: oops, WarHawk-AVG this is the 208mil version! We use 150mil.

ah poopy!

Thanks to all here who shared their experience and knowledge. I just want to tell with pride and joy that I got my first humble driver up and running.

Special credit with this goes to member wight, who provided invaluable information and took the time to help me through several obstacles in Eagle. I think it is fair to say that without his help this driver would never have seen the light of day. So again, thank you, Alex.

It’s basically wight’s 22mm 16x7135 driver, stripped down to 12x7135 to gain space for a larger spring pad and larger cable holes and pads, more space around the MCU for the clamp, while slightly reducing the diameter of the 7135s, so it can be filed down to fit even 21mm.
Picture shows the first 3 samples, I made a 24mm variante with a guiding ring for filing, as I needed a larger size for my test lights. Left is a fully transferred Nanjg 105c plus OTC, soldered with iron. Middle is a 12x7135, soldered with my new heat air blow gun thingy (Youyue858D+). Right is a 7x7135 with Zener Mod for an Ultrafire F10 with MT-G2.

They all work! It’s been like Christmas.

As these were a test run, I was pretty happy. But I already reworked the design, as I first went with 0603 components which are very difficult to handle. Will be 0805 now. In addition I improved some more like current paths, the position of components, the size of the text. Still in transit from OSHpark, but already obsolete… need to be tweaked for multiple PWM channels.

This is truly fun to play with.
