hello everyone.
I’m a light sculptor, and I use a lot of knowledge from flashlight to build my structures. so thanks guys for all your sharing.
lately I’ve been asked to build several lamps and I would like to power them with a USB source, so no battery.
normally I use a single mode 12v driver from DX because I need more than 2A,
but for this case I found only a 1.4A driver but the input is 4.2v so I have to add a diode to forward less current and I can’t keep all cooled.
can you tell me if something like this exist or how to build it?
+ 5.5v input, more than 2A but less than 2.5A, single mode, better if all the wiring is on the top side so I can attach a heatsink on the back of the driver.
or
I used some 220v 0.7A, that are very compact and works very well, but 0.7 is not enough.
is there a driver for an XML2/XPL straight from 220v and more or less 2A???
thanks a lot!
