Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

This circuit, designed on request, has proven to be useful to indicate when the voltage in a power supply line is changing from 120V to 240Vac. It can be used in different circumstances and circuits, ...

SEOUL, South Korea--(BUSINESS WIRE)--Seoul Semiconductor, a global LED manufacturer, today announced the release of another AC-powered LED solution in the Acrich2 family. The Acrich2 Linear Module ...

This file type includes high-resolution graphics and schematics when applicable. For applications such as motor control or power supplies, it’s often necessary to know whether the ac line is at 120 V ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

True to the history of other types of semiconductor products, LEDs offer better performance at a lower cost with every passing year. So much so, in fact, that the other elements of a conventional LED ...
