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

Product Overview

The LP3907SQ-VRZX/NOPB is a high-performance power management integrated circuit (PMIC) from Texas Instruments, designed for space-constrained applications requiring multiple voltage rails. Housed in a compact 24-WQFN (4x4 mm) package, it integrates two step-down DC-DC converters and two low-dropout linear regulators (LDOs), providing a complete power solution for processors, FPGAs, and other digital ICs. With input voltage range of 2.7V to 5.5V, it supports single-cell Li-Ion battery or USB power sources. The device features programmable output voltages via I2C interface, enabling dynamic voltage scaling for power optimization.
