Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close seriesA way of ...

In the ongoing drive to make circuitry ever smaller and more powerful, researchers in Canada have taken things to a very small extreme. They devised a method for turning individual silicon atoms into ...
