Figure 1: Simple flying capacitor circuit
Charge pump topologies and the precursors to charge pumps have been around for over 100 years. In the drive to make products smaller and more efficient, it may be the time to dust off the old flying capacitor and see what it might be able to do for you.
A “flying capacitor” is simply a capacit

Figure 1: AC-DC, Basic Voltage External Power Supply
External power supplies (EPSs) are contained in a separate housing from the devices they are powering and contribute substantially to total global electricity consumption. As governments strive to address their ongoing environmental responsibilities, resolving the inefficiencies of power conversion has become a

Figure 1: Typical application for an isolated power module
Every industry control circuit needs a supply voltage. But as the industry control circuit is only a small part in a bigger electrical environment, a lot of specification parameters have to be considered to choose the proper supply device. During the design of a DC/DC converter, the designer needs to know the inp
