When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

This is a quite simple DC to AC inverter that provides 220VAC when a 12VDC power source is provided. It can be used to power very light loads like night lamps and cordless telephones, but can be ...

As the number of Power Over Ethernet (PoE) powered device (PD) applications grows, market pressures are driving designers to lower the cost and complexity of the DC-DC converters that power them, ...

This file type includes high-resolution graphics and schematics when applicable. Low-power applications such as e-meters (electricity or energy meters) often require a simple ac line-powered supply ...

THE candle. It is a simple technology, and a good one. The electronic version is also simple to make, and is a great introduction to the concept of circuits – the cornerstone of many maker projects ...

Power Integrations has upped the output power if its LinkSwitch-TN2 ac-dc converter family with a device that can output 575mA – previously the top end was 360mA. “These new LinkSwitch-TN2 ICs are pin ...
