dc/dc converter, new PCB revision available

  redesigned the PCB! -no patches -high efficiency LED via 4.7k resistor -variable resistor to adjust quitescenct current -robust diode -imprint on the PCB for input/ouput, + and – this PCB can power small PIC circuits directly from 1.2 volts battery, as well it can replace 9v batteries, for instance it can generate small 12v currents from 2x AAA cells. … Continue reading
