Description | Small size, long lifespan, contactless, strong anti-interference ability, high voltage resistance between output and input insulation, unidirectional signal transmission, etc., widely used in electronic products |
---|---|
Application | Used in electrical insulation, level conversion, interstage coupling, switching circuits, signal isolation, pulse signal amplification, long-distance signal transmission, and input/output interfaces. In a switching power supply, a linear optocoupler can be used to form a voltage feedback circuit, which can adjust the control terminal current to change the duty cycle and achieve precise voltage regulation |
