Flyback switcher works down to 1.1V, flashes HBLEDs

This Design Idea shows a way to drive low-power electronic circuits using a single 1.5V cell. The design is based on a free-running oscillator that drives a flyback transformer to  generate a controllable higher voltage. It can be used to power analog circuitry, microcontrollers, and any other light loads. The power circuit was designed, simulated, and constructed. It was shown to operate reliably with a po ...
