Sure Electronics make this excellent SEPIC LED driver module, but there's some confusion over how to drive the enable input. Here I try to work out how it's done.

Where can I buy XL6006-based module (I need boost one)? I tried to search ebay and sureelectronics' items, but there is not any XL6006 there.
I like 0.22V feedback threshold, the XL6009 has 1.25, which results in unnecessary high power loss in constant current circuit.
Hi!
Can you more than 20W output measure? I have buying sepic converter with XL6009, i have tested, i have more, than 40W output power. I have XL6009 desoldered, and XL6006 soldered in the same PCB. Voltage divider is modificated, also i have 30V maximum. But i can not more, than 20W output become. 30V – 700mA, 20V – 1A, 12V 1.5A, 6,3V 2A, 5V 2.4A, and no more. With the original IC (XL6009) i have 5V 4A, 12V 3.5A, 18V 2.5A, 24V 2A, and 36V 1,25A. This is more, than 40W! What is with XL6006? Is it over power protected?
I have modificated this circuit what i seeing in datasheet, with 0.2ohm shunt. With 50W LED i become only 30V 0,7A… No more! With 0.1ohm (0,22V/0,1ohm->2.2A) i have 0.78A measured. This is not so good… Thanks!
Thnx a lot. just bought a 700mA sepic driver and your video is just an unexpected perfect find. You talk exactly what and how I'd like to hear ๐ Im trying to construct something similar myself.

thanks for this Justin, you used the enable Pin on the board block to test the function with the 1.2 volt battery which turns the driver off.ย Is it possible to directly connect the arduino to one of the pins to provide a similar function?ย I'm trying to create a strobe effect, 4-25 ms pulses for a short duration and then pause for 1 sec.
Which optoisolator did you use?
the are some way to modifi the current about 800mA???? that driver
keep up the good work man!!
