I have a peltier element ( [login to view URL]) and 12 LEDs (1/4 Watt). I need a circuit that boosts the Peltier voltage and with an adjustable constant current driver to drive the LED array.
A reed switch should be used to turn on and off the circuit. The circuit board dimensions should be pretty small maybe 1 inch by 2 inches. I am looking for a circuit board design including schematic, BOM, and gerber files for board manufacturing. The parts should be common parts and newark part numbers are preferred.
