Perhaps the simplest way to regulate a DC voltage is using a voltage divider and/or an active device like a Zener diode. Besides simplicity, they have the additional advantage of not being ...

Switching regulators with integrated power transistors provide simplicity, require few components, and make compact step-down power supplies. Few of these devices can supply more than 5A load current, ...

This circuit uses a step-up switch-mode regulator, which is usually used to produce a positive supply, to generate a regulated negative output voltage. The device used here is the MIC4680 from Micrel, ...

This article looks at how special converters equipped with PassThru mode can be useful when the circuit’s input voltage is too high or too low to power a load. It will give examples of how PassThru ...
