MPC18730 power management IC minimizes power consumption for battery powered consumer products
Freescale Semiconductor is extending its power management IC (PMIC) line with the MPC18730 PMIC for portable audio and video applications. The ultra-low, 0.9 V minimum operating voltage and low power consumption extends battery life — making the MPC18730 deal for battery powered systems such as portable media players.
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.
The MPC18730 operates from either a single cell Li-Ion (2.7 V to 4.2 V input range) or a single cell Ni-MH or alkaline cell (0.9 V to 2.2 V input range).
The MPC18730 uses SMARTMOS™ technology and integrates all functions into a single chip and small 9x9mm 64QFN package, making it an all-in-one product for power management — conserving space and perfect for portable applications.
