Optocouplers Market Analysis 2012-2017 and Forecast 2018-2023
An optocoupler, also called opto-isolator, optical coupler, opto coupler, photocoupler or optocouplers, is a passive optical component that can combine or split transmission data (optical power) from optical fibers. It is an electronic device which is designed to transfer electrical signals by using light waves in order to provide coupling with electrical isolation between its input and output. The main purpose of an optocoupler is to prevent rapidly changing voltages or high voltages on one side of a circuit from distorting transmissions or damaging components on the other side of the circuit. The Asia-Pacific Optocouplers market will reach xxx Million USD in 2018 and CAGR xx% 2018-2023. The report begins from overview of Industry Chain structure, and describes industry environment, then analyses market size and forecast of Optocouplers by product, region and application, in addition, this report introduces market competition situation among the vendors and company profile, besides, market price analysis and value chain features are covered in this report.
Flying promises the semiconductor to put out the lighting reference design of high light LED
A few days ago, flying promises the semi-conductive company (Fairchild Semiconductor) Employ the designer to bring one section and consult and design RD226 for LED, needn't have controlling circuit and optical coupler of secondary end, can implement AC input LED lighting system. RD226 is a common input 12W LED lighting solution, can reduce high light (HB)s The volume of the LED lamp, and material saving list Cost. The reference design adopt getting anti exciting topological the intersection of isolated form and primary-side control from converter, AC-DC of line, it is from 85VRMS to 265VRMS that common to input the voltage range, the line frequency is from 50Hz to 60Hz. RD226 offers 350mA and 700mA available constant current to export, the output voltage of the maximum of two is 17V. This reference design uses and flies FAN102 device which promises the semiconductor to control PWM control device as the primary-side, in order to reduce the overall system cost and volume.
It is high light (HB) that the tape has AC power input LED employ need one circuit change constant current into the intersection of AC and input voltage, in some application, because load must be isolated from power input, has increased design complexity. The classic method needs to use anti exciting type converter that constant current exports. In most cases, the secondary end controlling circuit will use an operation amplifier to cooperate with a reference circuit, or only regulate the electric current through the way that one control IC specializedly, and send the control information to PWM control device of the primary-side via the optical coupler. The innovative solution which promises the semiconductor flies, can let the designer realize that needn't have AC input LED lighting system of controlling circuit of secondary end and optical coupler.
Flying promises the semiconductor to offer the extensive reference design series, can reduce the space of circuit board, simplifies and designs, and guarantee the system reliability and accelerate the listing speed. These produce ready design, can play an important role, make, shorten and design time to OEM manufacturer, bring its application into the market more quickly.
