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 ...

Würth Elektronik has released a detailed and thoughtful app note on using opto-couplers, particularly ‘817’ types. AN0007a* ‘Understanding phototransistor optocouplers’ goes deep into analogue and ...

Optocouplers provide high-voltage isolation between a low-voltage device like a microcontroller or a pulse-width modulation (PWM) generator and a high-voltage device like an intelligent or integrated ...

This white paper discusses the use of hermetic optocouplers in military and space electronics applications. The use of hermetic optocouplers provide a highly reliable result compared to its plastic ...
