Mtn 17ddm in high amped configs?

I have a few of these, are they capable of 10+ A setups?

In a tripple led setup it should pull more than 10 with a good battery.
The output depends on battery, led, and resistance in the current path. Its a low resistance fet controlled direct drive driver.

With a Nichia Triple I’ve seen over 16 amps —-Also had trouble in very high amps triples with current ripple causing problems with the MCU resetting or going straight to Turbo
There’s a fix some one came up with —I think add a capacitor some where — I don’t recall

Hmm okay, it’s for a customer so might not be best for this scenario, thanks all!

Wish I had a few, been out of stock for awhile. Heat and noise can be an issue with high currents, but it is a good driver.

With good bypasses and good ground, I have had amp draws in the high teens.

EDC rotation:
FW1A, LH351D 4000k (second favorite)
FW3A, LH351D 3500k
FW3A, SST20 FD2 4000k
FW3A, Nichia 4000k sw40 r9080 (favorite light!)
FW3A, Cree XP-L Hi 5A3
Emisar D4V2, SST20 4000k
S2+, XM-L2 T6 4C

20+ amps on a 3v 50.2 and a 30T no issues…

Was this with the Mtn 17DDM driver or the A6 driver. I had A6 drivers that required the Del-djozz fix before they worked right.

Used the A6 in a tripple DQG tiny mod and pulled 17 amps. Driver would ramp into turbo and become unresponse until I added the fix.

It was with the 2 Guppy versions — the crazy part is some lights they work great others have the issue—-the A6 has always worked fine for me

Love the Guppy versions. Right now I am out of 17mm and 22mm FET+any number drivers. Waiting for Mountain to get stock again, Lisa says next month. Sad I have tons of bare OshPark boards, but my eyes and hands just keep getting worse, may try to build a 17 this weekend. I do tend to remove great current paths once a triple goes above about 15-17 amps, just no need for that much current.

Yeah, the only thing I can think of needing more than 18 amps in a triple is 50.2. Even Luxeon V and SST40 you don’t need more than 18, and that’s overkill for most everything else.

Good to hear Mountain will be restocking things… I’ve been looking for some 10440 FET drivers for a while. Fortunately, I also bought a house in the meantime, so I’ve kept busy…

I see they are now… They were not when I placed my order. Looking for the 22DDM and the 17DDM. Will wait for both to be instock, so shipping does not kill me. I would also really like to try this one out… 22mm 16× 7135 6A LED DRIVER
