LM26480SQ-AA/NOPB TI Power Management IC | 24-WQFN (4x4) | Dual Buck, Dual LDO

Product Overview

The LM26480SQ-AA/NOPB is a highly integrated power management unit from Texas Instruments, designed for portable and space-constrained applications. It combines two step-down DC-DC converters (buck regulators) and two low-dropout linear regulators (LDOs) in a compact 24-pin WQFN package (4x4 mm). This device provides efficient power conversion and regulation for multi-rail systems, such as those found in smartphones, tablets, and other battery-powered devices. The input voltage range is 2.8V to 5.5V, making it suitable for single-cell Li-Ion battery applications. Each output is adjustable via external resistors, offering design flexibility.
