ST-Ericsson introduces a family of power management components that claim a 30 per cent increase in talk time or Internet connection time of mobile devices compared to solutions that supply power directly from the battery improving battery life.

The PM3533 is an all-in-one solution that enables a device's dual-mode RF sub-system to operate with low cut-off voltage battery technology, thereby using all the energy available in the battery.

The PM3110 is DC/DC regulator that is 20 per cent smaller than other regulators designed for RF power amplifiers currently on the market.

The PM3533 and PM3110 dynamically match the power supply to the needs of the RF power amplifier, thus reducing the overall energy usage of the device.

Both are scheduled to be in volume production in Q1 2011.
