CY4N37 Products Detail

DescriptionSmall 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
ApplicationUsed 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
