New components extend mobile device connection time by 30% claims ST

According to ST, the power management components can extend the talk time or internet connection time of a mobile device by up to 30% compared with solutions that supply power directly from the battery. The PM3533 solution enables a device's dual mode rf subsystem to operate with low cut off voltage battery technology, thereby using all the energy available in the battery. ST says the device is 20% smaller than other dc/dc regulators and – along with its PM3110 device – is scheduled for volume production in the first quarter of 2011. Along with the PM3110, the company adds that the devices dynamically match the power supply to the needs of the rf power amplifier and "Matching energy supply and demand in real time is the key to ensuring that power hungry mobile devices can frequently connect to the Internet, access multimedia services and make voice calls without exhausting their batteries," said Patrick Dureault, vice president, Head of the Analogue and Mixed Signal business unit of ST-Ericsson. "Our two new solutions push forward the frontiers of power management technology and underline ST Ericsson's leadership in this important field."
