the led that i want to use is: sfh4715as with 1500ma max current. http://www.osram-os.com/osram_os/en/products/product-catalog/infrared-emitters,-detectors-andsensors/infrared-emitters/high-power-emitter-gt500mw/emitters-with-850nm/sfh-4715as/index.jsp?search_result=/osram_os/en/search/advanced_search.jsp?action=dosearch&inp_searchterm_1=sfh+4715as&website_name=osram_os_en
i am locking thiese two drivers:
1- 1520ma: **broken link removed**
2- 1400ma:http://www.fasttech.com/products/16...c7135-2-group-3-5-modes-led-flashlight-driver
I have also before used sfh4715s led with maximum 1A with driver 1050 ma, that was 50 ma overdrive, and it works fine,
I hope that the 20ma overdrive is not to much for this led am i right, what do you all think, or should i go with 1400ma driver, please some advise, thanks.
here is the datasheet of SFH4715AS http://www.osram-os.com/Graphics/XPic4/00168630_0.pdf/SFH 4715AS Lead (Pb) Free Product - RoHS Compliant.pdf
