The current trend of power ICs is not limited to a single function, but the various functions are integrated together, so power ICs are now more commonly referred to as power management ICs, or power management units (PMUs).
Industrial status of power supply IC
The power management IC industry should be an emerging industry. In recent years, the company with the highest growth rate has reached 70%, and the overall compound growth rate has reached 30%.
Power IC manufacturers are not monopolized by several major manufacturers in Europe and the United States. For example, Intel monopolizes 80% of the CPU market. The manufacturers of power ICs are more and more dispersed. The key is to find their own position. There are 11 power management IC manufacturers in Taiwan, and they are important industrial bases for power management ICs. Taiwanese manufacturers have a large scale of production and complete products, with an annual output value of nearly 100 million US dollars. The proportion of Taiwan's major power management IC manufacturers' products is as follows:
Power Management IC Product Project
There are about 10 companies in the mainland. The main manufacturers are Angbao, Shengbangwei, Changyuntong, Maxim, CoreSource, SMIC, Qida, etc. The products of mainland manufacturers are more specialized, the starting point is not high, and they have not formed a large scale, but each has its own characteristics. The patented “frequency shuffling†patent technology, such as the new technology, is used in most of its ICs, greatly improving system EMI performance and system design simplicity, reducing standby power consumption. In addition, in response to the "environmental protection" requirements, Angbao also introduced a green energy-saving AC / DC power control chip, its AC power adapter, charger, communication switching power supply, integrated LCD TV and display backlight power system, etc. It can significantly improve the energy conversion efficiency of the switching power supply system under light load and full load, and directly meet the various provincial power requirements in recent years.
Semiconductor manufacturers with analog products in Europe and the United States are almost all involved in the field of power management ICs, such as National Semiconductor, Texas Instruments, Maxim, Fairchild, ON Semiconductor, Intersil, Ricoh, and STMicroelectronics.
From the perspective of the global power supply Ic industry, it is still dominated by European and American manufacturers. Taiwanese manufacturers benefit from good relations with foundry manufacturers and system manufacturers, and are also in a good development period. Under the leadership of a group of returning scholars, mainland manufacturers are catching up.
