LM26480SQX-AA/NOPB TI Power Management IC | 24-WQFN (4x4) | Dual Buck, Dual LDO

Product Overview

The LM26480SQX-AA/NOPB from Texas Instruments is a highly integrated power management unit (PMU) designed for space-constrained portable 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 sequencing for multi-rail systems, making it ideal for battery-powered devices such as smartphones, tablets, and portable media players. With input voltage range from 2.7V to 5.5V, it supports single-cell Li-Ion battery applications. The LM26480SQX-AA/NOPB features programmable output voltages, independent enable controls, and built-in protection circuits including over-current and thermal shutdown.
