Austin, Tex.—Freescale Semiconductor's MPC18730 five-supply power management IC (PMIC) for portable audio and video applications works off as little as 0.9 volt, thus greatly extending battery life.
"With a minimum operating voltage of 0.9 volt, it’s possible to operate a portable device with just one battery, ultimately reducing the size of the device or extending the use," said Demetre Kondylis, general manager for the company's Sensors & Analog Products Division. “Designers and consumers can benefit from product miniaturization, increased portability and expanded battery life."
The MPC18730, which can work from a lithium-ion, NiMH, or alkaline source (2.7-4.2 volt input), includes two DC/DC converters to generate the main supply voltages and three series regulators for auxiliary rails. All five supplies are digitally set through a 3-wire serial interface. The interface also controls multiple power save modes, such as sleep, wake-up and on/off.
In single-cell applications, one DC/DC converter is configured as a buck-boost type, and the other as a boost regulator. These converters provide 0.8 to 1.5 volts at up to 100 mA, and 1.6 to 3.2 volts at up to 120 mA.
