The LP3972SQ-A413/NOPB from Texas Instruments is a versatile power management unit (PMU) optimized for low-power handheld applications and advanced application processors. It integrates six low-dropout linear regulators (LDOs) and three DC-DC buck regulators, along with a backup battery charger and two GPIOs.
The device supports dynamic voltage management (DVM) and features an I2C-compatible serial interface for software control of regulator functions and settings. The LDOs offer programmable output voltages from 1V to 3.3V with ±3% accuracy and various current capabilities, including LDO_RTC at 30mA, LDO1 at 300mA, LDO2/3/4 at 150mA, and LDO5 at 400mA. The buck regulators provide programmable output voltages from 0.725V to 3.3V, achieving up to 95% efficiency and a 1.6A output current.
Designed for applications such as smartphones, personal media players, and digital cameras, the LP3972SQ-A413/NOPB operates within a supply voltage range of 2.7V to 5.5V and has an operating temperature range of -40°C to 85°C. It is housed in a 40-WQFN exposed pad package, suitable for surface mounting.
Key features include thermal and current overload protections, ensuring reliable operation. The PMU is compatible with advanced processors requiring dynamic voltage management and includes automatic switching for backup battery chargers utilizing lithium-manganese coin-cell batteries and supercapacitors.
