The Texas Instruments LP3972SQ-A514/NOPB is a multi-function programmable power management unit (PMU) optimized for low-power handheld applications. It is designed for advanced application processors requiring dynamic voltage management.
This PMIC features three buck regulators and six low-dropout linear regulators (LDOs) with programmable output voltages ranging from 0.725 V to 3.3 V for the buck regulators and 1 V to 3.3 V for the LDOs. It supports an input voltage range of 2.7 V to 5.5 V and can deliver up to 1.6 A of output current. The device includes a backup battery charger with automatic switching for lithium-manganese coin-cell batteries and supercapacitors.
Key features include an I2C-compatible high-speed serial interface for software control of regulator functions and settings, as well as thermal and current overload protections. The LP3972SQ-A514/NOPB is supplied in a 40-WQFN (5x5 mm) package suitable for surface mounting.
Applications include smartphones, personal media players, and digital cameras, particularly those utilizing Marvell PXA processors or similar advanced application processors.
