Is committed to providing customers with excellent performance, reliable quality of photoelectric coupler (hereinafter referred to as light coupling), a power supply chip and isolation for the former vice edge circuit, switch signal transmission, and require high optical coupling isolation voltage, creepage distance conform to safety, to a certain temperature under the condition of stable work, use the accord with environmental protection certification of raw materials, etc.; At present, it is widely used in ultra-thin LED power supply, precision power adapter, small volume communication switching power supply industry.


The role of optocoupler in switching power supply is mainly isolation, supply reaction signal and switch function. In the switching power supply circuit, the power supply of the optocoupler is supplied from the secondary voltage of the high-frequency transformer. When the output voltage is lower than the voltage of the regulator tube, the signal optocoupler is connected, and the duty cycle is increased, so that the output voltage is increased. Otherwise, turn off the optocoupler and reduce the duty cycle, so that the output voltage drops. If the secondary load of the high-frequency transformer is overloaded or the switching circuit is faulty, there is no optocoupler power supply. The optocoupler controls the switching circuit, and then protects the switch tube from being broken down and burned. In this respect, we can consider our Orende industrial control grade transistor optocoupler series.
