LP3907SQ-TJXIP/NOPB TI Power Management IC | 24-WQFN (4x4) | Dual Buck, Dual LDO

Product Overview

The LP3907SQ-TJXIP/NOPB is a high-performance power management integrated circuit (PMIC) from Texas Instruments, designed for space-constrained and power-sensitive applications. Housed in a compact 24-pin WQFN (4x4 mm) package, this device integrates two step-down DC-DC converters (buck regulators) and two low-dropout linear regulators (LDOs), providing a complete power solution for multi-rail systems. The buck converters deliver up to 1.5A each, while the LDOs offer up to 300mA, with high efficiency and low quiescent current. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for battery-powered and USB-powered applications. Advanced features include dynamic voltage scaling (DVS), programmable output voltages via I2C interface, and comprehensive protection circuits such as overcurrent, overtemperature, and undervoltage lockout.
