Simple, (mostly) reliable, and based on decades-old technologies, we often take the optocoupler for granted, despite the vital roles it plays in many power applications. But we ignore these devices at ...

Although a monolithic low-dropoutregulator has superior dynamiccharacteristics, the discrete regulatorin this Design Idea is so simple that youcan adapt it to many purposes. Using acommon transistor, ...

In LEDs heat and high currents hasten the dimming process which can lead to unreliable operation in LED-powered optocouplers. Some simple and straight-forward analysis will keep their light shining ...

The ACPL-P340/ACPL-W340 gate drive optocoupler contains an AlGaAs LED, which is optically coupled to an integrated circuit with a power output stage. This gate drive optocoupler is ideally suited for ...
