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 circuit was designed to create a volume control with the use of optocouplers to produce a lightspeed passive attenuator. An optocoupler is a sealed device unit which has high performance LED that ...

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 ...
