LP3918TL/NOPB TI PMIC | 25-USMD | Multi-Channel Power Management, I2C Control

Product Overview

The LP3918TL/NOPB from Texas Instruments is a highly integrated power management IC (PMIC) designed for portable and battery-powered applications. Housed in a compact 25-pin USMD package, it provides multiple regulated output voltages, battery charging, and power sequencing in a single chip. The device features three low-dropout regulators (LDOs), a buck-boost converter, a linear charger for single-cell Li-Ion batteries, and an I2C interface for dynamic voltage scaling and system control. Its low quiescent current and high efficiency make it ideal for space-constrained designs requiring extended battery life.
