Figure 1a shows a latching circuit based on an optocoupler, IC 1. If the off switch remains closed, pressing the on switch powers the LED in the optocoupler. Thus, the transistor in IC 1 turns on. You ...

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 ...

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 ...

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 ...
