Has anyone looked into this 325/650 ma CC boost driver (other current levels too) to see if it is suitable for laser diodes? I'm getting no response from the seller, as of yet:
3 7V Lithium ion Battery Step-up Constant Current Driver LED Driver 18650 Boost | eBay
http://www.kin-track.com/userfiles/down/XL6003 datasheet.pdf
Seems this thing will keep pushing the voltage up to as high as 50 volts or until the current limit is reached, maybe a problem for laser diodes? If my diode starts pulling 650ma at a certain voltage, I'd expect that would be the highest voltage it would go to, but how about at power on, spikes??
I don't know why they list two or more LED's must be tied to the output, perhaps that is because the minimum output voltage is too high for just one. I'm wondering if this can be used to string several laser diodes in series with, or perhaps with just one diode, since some laser diodes can require higher voltage.
Specs state:
Input Voltage: 3.6V to 36V
Efficiency: 90%, Switching current max is 2A
Output voltage: Max 50V
Dimension: 30*13.5*5mm (Too big to fit our 11.9 mm modules with the back end cap).
Maybe it's junk, I've not had good luck with Chinese stuff but I ordered five of them to play around with, perhaps daring to hook up a laser diode to it after I scope it. Regarding my earlier comment that it appears it will push the voltage up to 50 volts until the current limit is reached, I don't mean to infer it can drive 650 ma anywhere near 50 volts, that won't happen. At least, not after the magic genie inside escapes in a puff of smoke or it just says no, can't do that.
