The Texas Instruments LP3971SQ-B410/NOPB is a multi-function, programmable Power Management Unit (PMU) optimized for low-power handheld applications and advanced application processors. It integrates three DC/DC buck regulators capable of up to 1.6A output current and programmable voltages from 0.725V to 3.3V, with efficiencies up to 95% and ±3% accuracy.
Additionally, the device includes six low-dropout (LDO) linear regulators for powering peripherals like the RTC, with programmable output voltages from 1.0V to 3.3V, ±3% accuracy, and various current capabilities (up to 370mA). It also features a backup battery charger and two GPIOs. Communication and control are managed via an I2C-compatible high-speed serial interface, allowing software control over regulator functions and settings.
Key electrical specifications include a wide input voltage range of 2.7V to 5.5V and a low quiescent current of 60µA. The LP3971SQ-B410/NOPB is housed in a compact 40-pin, 5x5 mm WQFN package with an exposed pad, suitable for surface mounting. The operating temperature range is -40°C to 125°C.
