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, […]
