BANGALORE: Freescale Semiconductor is extending its power management IC (PMIC) line with the MPC18730 PMIC for portable audio and video applications.
The 0.9V minimum operating voltage and low power consumption extends battery life - making the MPC18730 ideal for battery-powered systems such as portable media players, said the company in a press release.
"The name of the game in portable consumer devices today is battery life, battery life and more battery life," said Stephanie Guza, analyst for In-Stat.
The MPC18730 minimizes power consumption by using two DC-DC converters to generate the main supply voltages and three series regulators for the auxiliary rails. All five supplies are digitally controlled with digital-to-analog converters (DACs), through a serial interface. The serial interface also controls multiple power save modes, such as sleep, wake-up and on/off, making the MPC18730 ideal for long-life portable electronics.
It operates from either a single cell Li-Ion (2.7V to 4.2V input range) or a single cell Ni-MH or alkaline cell (0.9V to 2.2V input range).
"With a minimum operating voltage of 0.9V, 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 Freescale's Sensors & Analog Products Division.
"Designers and consumers can benefit from product miniaturization, increased portability and expanded battery life."
The MPC18730 uses SMARTMOS technology and integrates all functions into a single chip.
