IC(integrated circuit) It is a kind of micro electronic device or component, which uses a certain process to interconnect the transistors, diodes, resistors, capacitors, inductors and other components and wiring required in a circuit, make them on a small or several small semiconductor chips or dielectric substrates, and then package them in a tube shell to become a micro structure with the required circuit function; All the components have formed a whole in structure, which makes the electronic components take a big step towards miniaturization, low power consumption and high reliability. It is represented by the letter "IC" in the circuit.


DC-DC converter refers to a device that converts electric energy of one voltage value into electric energy of another voltage value in a DC circuit.

DC-DC is a newly developed miniaturized power switch module. It is composed of small surface mount integrated circuits and micro electronic components by using microelectronic technology. The use of DC-DC power module is conducive to simplify the design of power circuit, shorten the development cycle and achieve the best indicators. It can be widely used in all kinds of digital instruments and intelligent instruments.

DC-DC power modules are widely used in power electronics, military industry, scientific research, industrial control equipment, communication equipment, instruments and meters, switching equipment, access equipment, mobile communication, routers and other communication fields, as well as industrial control, automotive electronics, aerospace and other fields. Because the power supply system based on module has the characteristics of short design cycle, high reliability and easy system upgrade, the application of power supply module is more and more widely. Especially in recent years, due to the rapid development of data business and the continuous promotion of distributed power supply system, the growth of power supply module has exceeded that of primary power supply. With the extensive use of semiconductor technology, packaging technology and high-frequency soft switches, the power density of power module is becoming larger and larger, the conversion efficiency is becoming higher and higher, and the application is becoming simpler and simpler.
