This project is a variation on those using linear voltage regulator chips to power low-voltage experiments wherein it uses a low dropout regulator to allow lower input voltages and a fine adjustment ...

This design was conceived as an add-on for the Variable DC Power Supply, a very successful circuit posted to this website. This simple unit provides a dual-rail variable output ranging from ±2.5V to ...

It’s not entirely clear why [Advanced Tinkering] needs a 50,000-volt power supply, but given the amount of work he put into this one, we’re going to guess it will be something interesting. The stated ...

In many situations, designers must control the phase of an output signal in order to make certain circuits work properly. At low frequencies, an op amp can be used to vary the phase. But as the ...

A hybrid DC-DC converter topology boosts efficiency by combining a buck regulator and a charge pump. Is it the future of intermediate bus conversion?
