Hello everyone,
I am working on a project where I need to power 4 3-3.5v leds at aprox 1.5amps each wired in parallel. I can't wire them in series because they are non isolated and mounted to the same mcpcb.
I need the driver to be very high current and adjustable via a potentiometer or some other sort of dial control. I would also like it to be possible to run on several 18650s in parallel. I could do series but parallel is preferred if it's possible.
I considered running several lm317s but the input voltage wouldn't work and efficiency would be pretty bad as far as I can tell.
Anyone have suggestions either diy or modifying some available current regulator?
