New generation of power supplies will be needed for mobile market

18 July 2001 Power Electronics / Power Management

While the whole world awaits more advanced mobile Internet devices to come into the marketplace, it is a new generation of power supplies that will allow these devices to be as useful as imagined. According to Allied Business Intelligence (ABI), as users try to replicate their 'always-on' Internet experience on a mobile device, many will find that the power supply for these next-generation clients are insufficient in both battery life and standby time.

"Semiconductor chip performance has risen over 3000% in the last decade, yet battery performance stood at a minuscule 80% enhancement," said Atakan Ozbek, ABI's Senior Energy Analyst. "The power demand of next-generation wireless devices will sharply increase, but if battery performance and reliability do not answer handset manufacturers' demands, that might curb the growth of the sector."

Mobile commerce and mobile applications will require much more complex mobile devices, including those that combine voice, data and multimedia applications. "To allow these complex devices with long component chains to perform properly, next-generation power supplies, those that are highly efficient and possess a higher energy-density ratio, are going to be needed," Ozbek said.
