Reducing the "occupied area" of electrical and electronic devices and devices is the focus of all market areas around the world. In recent decades, the number of electricity used by ordinary citizens in developed countries has increased significantly, and the amount of energy use has increased almost accordingly. In addition, the demand for technology in developing countries is increasing rapidly. It is easy to see that the pressure of generating electricity is huge because of the related environmental impact. If not controlled, estimates that global electricity consumption in 1990 from about 200 TWH (TWh) increased to more than 1600 in 2030 TWh.

　　Electricity production is a major factor in global warming. The fear of global warming has led legislation around the world to support, promote or even require more energy efficient products and equipment for consumption and industrial fields. Many of these plans have been fruitful and continue to be implemented effectively, but with the rapid rise in the use of energy, there is still important work to be done. Another incentive for Industry and consumers is, of course, rising energy costs.

　　Energy saving design is not new, for example, portable battery powered products have been designed to continue to use for as long as possible between batteries. Cell phone is a good example. Customers need small volume, light weight, more powerful functions and longer battery life. Manufacturers have clearly achieved these goals, but it needs to dramatically change the technology of cell phone and battery design. Companies like A Morimi semiconductor have made significant contributions to this success through advanced power management device technology and recent "intelligent" charging scheme.

　　The front-end technology itself in many aspects of the evolution of the total power to help offset some of the increased requirements, such as LED and incandescent lighting and TV for relatively stable real opportunities for increasing energy use, is of low power consumption technology, process and devices used in circuit design, to provide efficient power conversion and more and more intelligent power management.

　　A Morimi semiconductor, which acquired Fairchild at the end of 2016, has become the second largest supplier of power semiconductor discrete devices according to market share. Fairchild's high-voltage product expertise and product lineup is complementary to A Morimi semiconductor's low power expertise. Now the company has a full range of power conversion and power management technology. This enables the semiconductor to have unique advantages to support customers in many fields to achieve their customers' energy efficiency level and increasingly stringent regulations.

　　If we are to achieve the requirement of improving energy efficiency and the corresponding slowdown on power, so it is essential to solve all the challenges including the voltage range, from 480 V three-phase power grid and power distribution is applied to high pressure industrial equipment, and then to low to drive a small load in daily life such as see is usually used in portable equipment, CPU, and DSP memory.
