The global power management semiconductor market will grow 13.9 percent to $36.2 billion in 2011 as the need for energy efficient equipment continues to increase, according to researcher IHS iSuppli.
"The increase in power management revenue in 2011 follows a 'banner year' in 2010, when power management semiconductor sales increased 41.6 percent to $31.8 billion from $22.5 billion in 2009," said Marijana Vukicevic, principal analyst for power management at IHS iSuppli. "Sales in 2011 simply will not be able to keep pace with the rapid expansion of 2010, when revenue rebounded dramatically from the recession year of 2009."
Driving power management semiconductor demand is the move toward more efficient battery-powered devices. Consumers want longer battery life in their cell phones, notebook computers, portable navigation devices and other equipment, which means greater demand for power management integrated circuits.
Alternative energy systems such as solar and wind, electric vehicles and smart meters are also driving power management IC demand. Demand for those products and systems are growing.
Power management ICs include voltage regulators and references, power management ASSPs/ASICs, drivers, power transistors and rectifiers.
