In isolated power supplies, optocouplers pass the feedback signal across the isolation boundary. Optocouplers contain both a light-emitting diode (LED) and a photo detector. Current flowing through ...

An optocoupler-isolated power supply is often the safest and most practical way to go when it comes to performance and protection. Here's the basics on today's LED/photodetector isolators and what you ...

The importance of signal isolation in high-voltage design The difference between optocouplers and opto-emulators Details on TI’s silicon dioxide (SiO 2) isolation technology Isolation is invaluable in ...

Switching power supplies, operating directly from input power lines, are generally required to have their outputs galvanically isolated from the input, in order to reduce the danger of electrical ...

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 ...
