New Type DC-DC Converter Mod

[breaktru]

You sure you didn't have a capacitor up your sleeve?

Actually, nice to see that small of a voltage sag!

Don't get me wrong, I don't mean to push the .44 as a powerful boost mod. It has it's place in the mod world as an easy to carry, convenient little "On the Go mod". Nice for stealth vaping. I have tried it with many size atty/carto sizes/brands and it handles them quite well. But there is one carto that it struggles with and it's the 2.0 ohm Boge carto. The best vape is with a 2.0 standard atty. Go figure. I thought 2 ohms was 2 ohms.

Dave I warned you about those mod cops coming after you!!!!!!!!

Links? Their product line is vast and I didn't see anything off-hand.

One device I used recently I thought was cool is this little buck converter. I used it to make a couple USB cig lighter adapters. Automotive stuff has to have at least a 35V tolerance (due to nasty voltage transients than normally occur in automotive electrical systems). That stuff is not easy to come by. I load tested it and even though it says the current limit is 1.5A, it can put out 2A continuously with little voltage sag. Be a good one to use for a direct USB passthru in the car if you use an atty 2.5Ω and higher.

Links?

Uuuuuuuuuum, pfffff, yeah right. I'm not the expert Craig, I'd have to search a lot harder than you to find it, I was just curious to see if you have seen what's in their e-mail updates and if you've used any new stuff?

Maybe when I'm bored out of my mind I'll surf through there and make a fool of myself and give you links that probably don't apply...? LOL

Yeah I've seen this before, but its a fixed output, correct?

Why not just use the OKR series that has an adjustable output?

Is it because the input maximum level is too low, 14V instead of 35V?

Well if you're makin' stuff Craig, go on over to Tru's site and posted some pictures man!

Better yet, do a tutorial!!

Nice little device used at the 12 volt input of almost every disk drive would take care of that. And a ferrite bead to keep the OK-R from talking back to you through the radio

Pfah. Everybody knows you don't think its the baddest vape monster ever. Most everybody at least. These 2AA size things are just the right size to me for running around. I've tried smaller (little sister) and its too small for my ape hands to be comfortable with. I don't get these 12-watt folks anyway. I don't want something on fire in my mouth anymore, I'm over that!

Problem with automotive electrical is that surges happen frequently and will burn out a suppressor that engages anywhere near normal system voltage. None of the suppressors I've come across can absorb surges indefinitely. Normally, you use stuff that's 35V tolerant and employ surge suppression to cover severe transients above that, for example, load dumps that can happen when using jumper cables to start another car.

I used a bidirectional TVS diode in combination with a Schottky rectifier in the USB cig lighter adapters I made. Since I plan to use these to charge my mods, I want them to be as robust as possible so as never to damage my mods. You might be surprised to find that most USB cig lighter adapters have no surge protection whatsoever, let alone the utilization of a switching regulator.
