Optocouplers are used extensively for high-voltage isolation and electrical noise rejection – two essential requirements for transmitting correct information between different voltage potentials ...

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 ...

It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

Designers of switch-mode power supplies generally put a lot of care into selecting the placement of poles/zeros of the supply transfer function to ensure stable operation. However, many such designs ...

Deep in the heart of your latest project lies a little silicon brain. Much like the brain inside your own bone-plated noggin, your microcontroller needs protection from the outside world from time to ...

The optocoupler continues to evolve to meet increasingly stringent requirements emerging from power-conversion apps, where safety is a top design driver. This week's PowerBites focuses on some recent ...

VMI’s new High Voltage Optocoupler design allows for low voltage LED control of a high voltage diode. In a convenient surface mount package, VMI has minimized the size of an optocoupler with up to ...

Utilizing the photo-sensitive nature of silicon, VMI has created a line of hermetically sealed, high voltage optocouplers and opto-diodes in versions that can be assembled in series configuration for ...

Over the years we’ve seen several attempts at adding Internet connectivity to the lowly wired doorbell. Generally, these projects aim to piggyback on the existing wiring, bells, and buttons rather ...
