It is widely used in communication equipment, including batteries, and solar energy systems.
The DC/DC converter is a newly developed miniaturized power switch module, which uses microelectronics technology to assemble small surface-mounted integrated circuits and microelectronic components into one body. The use of DC/DC converters is conducive to simplifying the design of power circuits, shortening the development cycle, and achieving the best indicators. It can be widely used in power electronics, military industry, scientific research, industrial control equipment, communication equipment, instrumentation, switching equipment, access equipment, and mobile Communications, routers and other communication fields and industrial control, automotive electronics, aerospace and other design fields.
Due to the short design cycle, high reliability, and easy system upgrade characteristics of using modules to build power systems, power modules are becoming more and more widely used. Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the increase in power supply modules has exceeded that of primary power supplies. With the extensive use of semiconductor technology, packaging technology, and high-frequency soft switches, the power intimacy of power modules is increasing, the conversion efficiency is getting higher and higher, and the application is getting easier and simpler.
