New 9000/5000mA buck and 2050mA boost drivers

9000/5000mA buck driver -> http://pcb-components.de/index.php?...roduct_id=108&option=com_virtuemart&Itemid=64


2050mA boost driver -> http://pcb-components.de/index.php?...roduct_id=107&option=com_virtuemart&Itemid=64


I just saw they have 2 new drivers and the specs look awesome! I dont think many of you know this site so I post it here. :wave:

Looks very nice .

Possible to PWM input the drivers as well, so possible do make a multimode driver for full SST90 potential. That's about time .

Anyone tried it yet?

Hmmm they do look good, especially the 9A version. Could this possibly be used to drive 3 strings of 3 XM-L LEDs? so 3s3p. 10.5V @ 3A per string?

Interesting driver. I wonder if they will operate over a wide temperature range ?

My German is almost non-existent, but with Google Translate:

Ausgangsspannung bis ca. 14 Volt (entspricht z.B. 3 Stck. SST90 Leds)/Output voltage up to about 14 volts (equivalent to eg 3 pcs. SST90 Leds)

makes me think you can, with the caveat that you'd need an appropriate power supply for the whole thing.

Helloooo active cooling!

If it gets hotter than 85°C it turns the output down by itself.

The last thing it needs is a secondary board with PWM

Yes, but will it run when it is really cold out (like -40 C). That is what separates the men from the boys.

Just noticed that KD has some new 9amp drivers here. They have a 5 mode version and a 3 mode version low,med and high. I know that there probably not going to be 9amps truly. But they do look beefier than what i was use to. This may be another option.

If you want I can ask the shop for you. :thumbsup:

Or your german is so good that you can ask yourself. (I don't think its that good :nana


Not that anybody thinks that I make those drivers. I just saw them when I was shopping for my current project.

Not really an option in my opinion, it's freaking huge . It doesn't even fit in a maglite.

I like the taskled driver, but thats around 2mm to big for a surefire m series. To bad
