Combining the operation of a boost regulator and a negative voltage converter can generate a negative supply from a single low voltage supply. The circuit in Figure 5 shows a standard application ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

Electronic circuits typically operate from regulated positive output voltages, often provided by buck regulators. If a negative output voltage is also required, the same buck controller often can be ...

The power supply that's described here boosts the voltage from a 1.5-V flashlight cell to 3.5 V across an LED, while the LED and flashlight cell are in series with the power supply. What spawned this ...

Switching power supplies are familiar to Hackaday readers, whether they have a fairly conventional transformer, are a buck, a boost, or a flyback design. There’s nearly always an inductor involved, ...
