NJG-18, multimode boost driver for 445nm.. and possibly 650nm

4.5A@4V to put out 1.7A? Not the epitome of efficiency there. heh

Yep and hooked it up to a diode and it gave me a whopping 1200mW and started dropping like a stone. It was still pulling 4.5A and the positive spring gets smoking hot. Actually burned the crap out of my finger. I am felling this is a lost cause.:cryyy:

Damn!

 

[DTR]

Yep I have suffered enough damage and I am frustrated so I need to give up while I am behind before I loose a diode.:tinfoil:

I guess it is back to waiting on flexdrives for single Li-Ion 1.8A builds.:cryyy:

 

[bhwollen]

Damn. Thats like a $50 driver!

Point of reference - when the AK-007 driver I found hits 820mW (raw optical output), it is drawing 1.9 A.

 

[steviedezie]

well its been like what... 2 months now that the flex's have been out. damn, how long does the manufacturer take to make these.

Can you test the exact mA with a freshly charged battery?

[rhd]

This was a fresh charged battery (16340, trustfire gray)

Because of that build style, I can't test the mA to the diode anymore, unfortunately, just the optical output.

I'm interested to see if these are usable as a dual driver build.

 

[steviedezie]

what the ak-007 drivers???

 

[bhwollen]

Look for a thread rhd made. Its like a just under 1w $3 boost driver.

 

[rhd]

A very very new, untested, driver

I've only owned 3, so it's definitely pending some more confirmation from the community

 

[bhwollen]

Well I just bought 10. Hoping I can get 900mA out of them.

 

[steviedezie]

well the question is, can those AK-007's be run in parallel. IF so...thats like a 1.7-1.8A boost driver for 6 bucks.

 

[bhwollen]

Thats what I was implying in the post above
