Default O-like 1.5A adjustable driver

Has anyone used these? I am trying some out but I can't get more than 1A out of mine. Is there something else besides the potentiometers that you need to adjust to get the 1.5A?

Default Re: O-like 1.5A adjustable driver

what Vin are you using?
might be like the flexdrive, to hit the full 1.5A you need a high Vin, for flexdrive its 5V instead of the 4.2V that are lithium batterys use.

Weird on the eBay add it says 3.7-4.15V

Ramp the Vin up and see if it outputs more current?

Yeah it is sensitve to the Vin. It is just too bad I don't have a 5V battery to use.

Default Re: O-like 1.5A adjustable driver

yobresal;

How much more current do you need ?

There are some new 18650 which output 4.35 VDC,

slightly more than the 4.2 VDC of older types.

They should offer about 5% more voltage,

which should deliver a larger percentage of current increase.

Well I'm using a 26650 otherwise that would be prime. Thanks though! Actually it would fit just fine with spacers around it.

Default Re: O-like 1.5A adjustable driver

they dont mention anything special to hit 1.5A.
Are you powering 445 or 405?

Edit:
actually i doubt you would be running a 405 at that current, so i dont know.

Default Re: O-like 1.5A adjustable driver

Yeah forget about driving a 405nm with these and a single lithium cell. Just tried it. The diode puts out 100mW max (12X diode)
These are perfect for driving a 635nm diode though. Works great on that at least. In fairness they are good at driving 445nm diodes just don't expect to get more than 1.2A

Default Re: O-like 1.5A adjustable driver

Hi yobresal

So you couldn`t get more than 1.2A with one cell? Thats not good
You could try to by pass the pot with a wire.

Have you tried the other one? the 600mA one?

Default Re: O-like 1.5A adjustable driver

yobresal;

On the website it states (<1.5 amp) .

Not good for a spec.

Higher voltage and less I.R. should get you slightly more current.

Default Re: O-like 1.5A adjustable driver

Does it? Yes, it also says "adjustable to 1.5A"
I have decided to keep these around for driving any other future 635nm diode I pick up. They are good for 445nm diodes to if you are looking for 1-1.3W Maybe I will use them for that too. They don't put out the voltage for 405nm diodes so don't bother.
I suppose they are good for the price. Just wish I hadn't bought 10 of them.

Default Re: O-like 1.5A adjustable driver

Does it output 1.5 amps into 3vdc? A flexdrive won't do 1.5 amp unless it's got almost 5.5vdc input or you're powering to like 3vdc, like a red 635nm diode for example. Man I was really hoping these little babies would be a 405nm 12x, 445nm AND 635nm driver! I've got a small order of them on the way from o-like.
They might just be an adjustable version of their fixed output 1.1 amp boost boards.

Default Re: O-like 1.5A adjustable driver

First of all,
HI I'm new here, that's my firsth post.
I've bought these driver from O-like to and I cant get more than 630mA from it with a single li-ion cell (4.09V max charged) is it due to the V-in as said some post before?

Has anyone tryed other V-in? 8.2, 8.4?

Maybe O-like have shipped me the 600mA adj driver instead of the 1.5....

Sorry for my bad english,
The forum is AWESOME!!

I'm not familiar with this driver but it's definetly a boost driver. You should never have more then 5V going in to this driver. At 8.2v-8.4v you'll kill it instantly and possibly the diode too ( depending on the protection of the driver) and about it outputting only 600mA then you could have got the wrong one or a faulty one


And since youre new here welcome to the forum

Got what i was looking for sorry for the post and delete, the pot that is closest to the spring bounce is the one that adjust the output to the diode.
