The LP3971SQ-B410/NOPB from Texas Instruments is a multi-function, programmable Power Management Unit (PMU) optimized for low-power handheld applications. It is designed to power advanced application processors and provides a comprehensive power solution.
The device integrates three DC/DC magnetic buck regulators capable of delivering up to 1.6A with programmable output voltages from 0.725V to 3.3V and up to 95% efficiency. Additionally, it includes six low dropout (LDO) linear regulators for powering peripherals like the RTC, with programmable output voltages from 1.0V to 3.3V and output currents ranging from 30mA to 370mA. The LDOs offer ±3% output voltage accuracy and a typical dropout voltage of 100mV.
A key feature is the I2C-compatible high-speed serial interface, which allows for software control of regulator functions and settings, including individual regulator output voltages and on/off control. The LP3971 also incorporates a backup battery charger with an automatic switch for coin cell batteries and supercapacitors. Protection features include thermal overload and current overload protection.
This PMU is housed in a tiny 40-pin, 5x5 mm WQFN package, making it suitable for space-constrained designs. It operates within a temperature range of -40°C to 125°C. The standard package quantity is 1,000 units on a small tape and reel.
The buck regulators have a programmable output voltage range from 0.725V to 3.3V.
The buck regulators can deliver up to 1.6A of output current.
The LDO regulators have a programmable output voltage range from 1.0V to 3.3V.
The LDO regulators offer output currents up to 370mA.
The typical dropout voltage for the LDOs is 100mV.
The operating temperature range is -40°C to 125°C.
This component is in a 40-pin WQFN package.
