I really believe for our application they are not nessessary. a lot of these non-isolated modules are used on servers and telecom equipment where line noise could be an issue. we really don't care about that, in my opinion.
I actually just used the datasheet and went from there. It's like an instruction booklet. It's not any different (except chip pin-out) then okr-t10 schematic, just the resistor for the pot. I used a 1k (I think) set resistor with a 2k vishay pot. And also a 1.4k pull up resistor. If I ever get some time I'll try and write out a schematic for you. One little issue with this board, I didn't notice until recently. It's limiting me at around 75 watts for some reason. I think maybe it would like an 11v battery instead of a 8.4v battery. Either way, I have built 2 of these TDK mods and they work great.
I take it back. I think it might have been the error in the pot, or it was sticking. I just tried it and got 6.66V with a .48 coil. which is around 100 watts. I'll have to try it on my other one. it was happening to both of them.
This charger can discharge the battery and recharge from a completely dead state, I'm assuming this refreshes the battery's memory so that it will continue to have complete capacity.
Great job Uncle Tat!What chip did you use? The iAF12020A007-003-R or iAF12020A007-007-R? The iAF12020A007-007-R is rated to have on board capacitors as far as I understand.A schematic would be awesome if you have the time. Pics too! Box porn is always awesome.Ive picked up everything to build a couple Lambdas but just haven't had time.In the mean time I'm embarrased to admit that I broke down and bought a IPV3 150w and a Yihi SXmini 60w.These are my first two regulated mods. Still playing with different atomizer setups. One thing I've learned is that 150 watts is a lot of POWER. The SXmini is an AWESOME mod! 45w seems to be plenty of power for my all day Orchid atty at .5 ohm.I'm really hoping to build these Lambdas as compact as possible so I can get more life between charges.Really liking the look of the Zero mod. I might shoot for that type of design rather than doing the Hammod box thing.
