Utsource APIC-S03 Optical Coupler IC Chips review

The types of optical coupler
The optical coupler has two kinds of package forms, such as double line, tube and optical fiber, which have dozens of kinds. There are 8 typical products :(a) general type (without a base lead); (b) general type (with a base lead); (c) darlington type; (d) high-speed type; (e) optical integrated circuits; (f) optical fiber type; (g) photosensitive thyristor type; (h) photosensitive field effect tube type.

Performance characteristics of optical coupler
The main advantage of optical coupler is one-way transmission signal, and the input and output terminals completely realize electrical isolation, strong anti-interference ability, long service life and high transmission efficiency. It is widely used in level conversion, signal isolation, isolation, switch circuit, signal transmission over a long distance between level, pulse amplification, solid state relay (SSR), instruments and meters, communication equipment and microcomputer interface. In the single-chip switching power supply, the linear optical coupler can be used to form the optical coupling feedback circuit, which can change the duty ratio by adjusting the control terminal current to achieve the precision stabilizer.
