National Semiconductor Corporation introduces its flexible power management unit (PMU) with an integrated buck-boost converter. Well suited for energy-sensitive portable media applications, the LP3910 PMU includes a dual-source battery charger to power a device from a wall adapter or USB and a digital I2 C compatible interface. The integrated battery charger supports power routing which allows system usage immediately after an external power source has been detected. The I2 C interface allows the customization of electrical specifications, such as output voltage and switching modes, to the end application. The digital interface provides the flexibility to use the same device for multiple tasks that require different output voltages.
