It may be faster to look up a LED driver schematic and build your own.
yea sadly they don't seem to exists. so i bought a resistor programmable eval board from digikey. hopefully that does the trick.
normally i would just use a resister. but that's not very efficient. and for a solar light. that is the last thing you want is to burn off most of your energy as heat in a resistor.
