Power Management IC (PMIC) for Advanced Application Processors

Description

The LP3971 is a multi-function, programmable Power Management Unit, designed especially for advanced application processors. The LP3971 is optimized for low power handheld applications and provides 6 low dropout, low noise linear regulators, three DC/DC magnetic buck regulators, a back-up battery charger and two GPIO’s. A high speed serial interface is included to program individual regulator output voltages as well as on/off control.
