Single and Two Cell White LED Drivers Without Inductors
Three inductor-free circuits that allow a white LED or UV LED to be driven from one (1.5 volt) or two flashlight cells (3 volts total) are described. The circuits on this page are: The two cell (3 volt) circuit four transistors. The simple single cell (1.5 volt) circuit requires six transistors, but it isn’t as […]
