GaN Energy Efficient Technology Is Driving Demand For PMICs

Gallium nitride is overtaking silicon carbide for use in power semiconductors (which use PMICs), as it enhances power density, breakdown voltage, switching frequency, resistance and system efficiency.


Power Management Integrated Circuits (PMICs) accounted for 3.5% of the global semiconductor market in 2010, according to a new report available on 

PMIC market growth is driven by consumer interest in portable devices such as smartphones, and their need for energy efficient technologies.

PMICs have applications in the communication, IT, industrial, automotive, medical, defence and electronics sectors. A factor encouraging growth in the PMIC market is the interest in energy efficient technologies, to combat rising energy prices and consumer adoption of portable electronic devices. 

Alternative energy technologies used to harness solar and wind power are driving demand, as power semiconductors use power management integrated circuits to minimise energy wastage and ensure efficient power distribution. The PMIC research report, “Power Management Integrated Circuits (IC) Market to 2020 - Alternative Energy Markets and Energy Efficient Portable Gadgets to Drive Sales Growth," indicates that energy efficient technologies could reduce global electricity use by up to 30%, by 2025.

Manufacturing companies are seeking improvement opportunities for their power devices, and substrate technology is of interest. The power management integrated circuit research report highlights a trend for the use of GaN instead of SiC in power semiconductors (which use PMICs), as it enhances power density, breakdown voltage, switching frequency, resistance and system efficiency.

Thermal management is another opportunity to minimise cost and improve efficiencies of power management semiconductor PMICs. Improvements to packaging systems will equip PMICs to cope with fluctuations in current, and subsequently enhance energy management.

Key companies profiled within the PMIC research report include: Infineon Technologies AG, Linear Technology Corporation, National Semiconductor, STMicroelectronics N.V and Texas Instruments.
