Due to the large-scale application in smartphone, tablets and other portable equipments, power management technology gains increasing traction while bringing new challenges. Power management IC includes a variety of categories, such as LDO, DC-DC、Driver and PMU. In recent years, with mobile phones and other devices enhancing requirements for power management, some discrete power management chip, comprising LDO, DC-DC have been integrated into power management unit (PMU). Power management IC will see explosive growth in multiple fields.
In 2013, the largest highlights in China’s mainland IC market is high-performance, low-power processors, wireless communications, power management, and high-speed mass-storage chip. According to IHS iSuppli, the power management IC in 2013 will reach $32.2 billion, an increase of 7.6%. In the coming three years, the market will maintain moderate growth with operating income in 2013 expecting to amount to $38.7 billion. Consumer electronics, network communications, mobile Internet field are the major segments; automotive electronics, new energy also starts the growth.
During the IC China 2013, many Chinese local Fabless have launched their power management IC product. With the gradual expansion of panel application, such Taiwan-based manufacturers as Richtek all enlarge layout in panel market. Chipone from Chinese mainland introduced the panel-targeting PMU product-9101A which enables to achieve the solution of “integrating three screens”. BYD brought ICBT, current sensors and other products. The general manager assistant in BYD Company Limited, Wei Yong said “2013 is the first year for electric vehicles taking off; the soar of which will form a large pusher to increase the revenue of power management IC.”
Fueled by government support, smart grid gains growing traction. Yu-tai Technology focuses more on input chip buck ETA2821 and 2841, which is dominated by MPS and
TI. The device has the advantage of small size, high efficiency, up to 42V durability and wide range of operating voltage, suiting industrial electronics. In addition, it is also found in LED drive, vehicle charging and other areas.
