According to an IHS iSuppli Power Management Market Share and Supplier Analysis report from information and analytics provider HIS, Texas Instruments Inc remained the leading manufacturer of power management semiconductors after an important acquisition, commanding a full 10.0 percent share of market in a highly fragmented field of more than 100 suppliers last year.

With 2011 power management revenue generation of $3.18 billion, up a solid 25 percent from $2.54 billion in 2010,TI easily held off French-Italian entity STMicroelectronics and Infineon Technologies of Germany, both unmoved from the second and third spots, respectively, that they held down the previous year when TI was also at the top. STM had power management revenue of $2.25 billion, down from $2.29 billion—decent enough for a 7.1 percent share of market. For its part, Infineon saw revenue climb to $2.09 billion, up from $2.00 billion, giving it a 6.6 percent market share last year.

The market for power management semiconductors includes products related specifically to the conversion, distribution and management of power in electronic systems. Integrated circuits like voltage regulators and references, as well as power interface ICs and application-specific power management ICs are Among such products. Other important power management products include power discrete, such as power transistors greater
Acquisitions in the year also helped boost the standing of many of the acquiring companies A notable accomplishment was that of Japanese supplier Mitsubishi, which took the lead in power transistors over Infineon for the first time, and made the jump from eighth place in 2010 to No. 4 in 2011 with revenue growth of 52 percent—the highest in the Top 10. Mitsubishi’s leap displaced fellow Japanese firm Renesas Technology, which tumbled to fifth place, down from fourth.

For power management companies, especially the smaller firms, to blindly follow such a uniform prescription in the quest for expansion could serve a recipe for disaster.

All power management companies embarked on the same voyage this year. Compounding the problem, a number of forward-looking companies have made that transition sometime ago and were already strong in those high-value markets.
