Description

The LP3972 is a multi-function programmable power management unit (PMU) designed especially for advanced application processors. The LP3972 is optimized for low-power handheld applications and provides six low-dropout low-noise linear regulators, three DC-DC magnetic buck regulators, a backup battery charger, and two GPIOs. A high-speed serial interface is included to program individual regulator output voltages as well as on and off control.
