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, ...
Figure 1: In a step-up converter, all you have to do to change the output voltage is change the duty cycle of the switching signal. Interestingly, the circuit raises the voltage by changing the duty ...
A highly integrated step-up dc-dc converter and power management IC can start up and run from either plus or minus millivolt input sources, making it ideal for energy harvesting applications in which ...
