Hello,
thank you very much for the answer. I will buy the 5015 as you recommend.
My project is a DIY bike light based on 4 Cree XML2 wired in series, that I want to drive at 3 Amps.
At the beginning of my project, I was looking for a step-up (boost) converter, to use small batteries like 3 or 4 cells lipo pack.
But I really like the display for easy setup and monitor live the amps given to the LEDs, and also the Vin to alert me when my Lipo pack voltage will be too low.
Unfortunatelly, it is a buck converter, so Vin must be greater than sum of LED’s forward voltage (about 14 volts for 4 LEDs), so i need to use “big” battery 5 or 6 cells.
My initial idea was to have 6 Cree XML2 in series, so a total forward voltage of 21 V and so a power output of 63 Watts !
Unfortunatelly, I do not find any cool boost module (except hbflex from taskled) with good specifications and display (voltmeter, amp meter,…).
Perhaps the solution will be to connect in parallel 2 clusters of 3 XML2 in series to the 5015 ? In this case I will have to setup the 5015 to output 10.5 volts and 6 amps, should it work ?
Thanks again
