Having found that the only two slotted opto-couplers in the miscellaneous draw were faulty, I managed to cobble together one that functions out of bits of the broken ones. It is amazing how this quick ...

Traditionally, isolated power supplies use an opto-coupler in the feedback loop to transfer regulation information across the isolation barrier. Unfortunately, an opto-coupler’s gain characteristic ...

Silicon Labs has introduced an all-CMOS drop-in alternative to high-speed digital opto-couplers, claiming that it offers longer life than traditional LED/photodiode isolators plus lower input turn-on ...
