When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

Shortly after installation, the simple water-leak-detector circuit in this Design Idea saved the day and hundreds of dollars. The average life expectancy of a hot-water heater is about 10 years. It’s ...

This gate-drive transformer (GDT)circuit allows the drive signal to the MOSFET to range from 50% down to 0%, while still offering a fast turn-off that cannot be accomplished with a simple load ...
