LP873345RHDT TI Power Management IC | 28-VQFN (5x5) | Dual Buck, LDO

Product Overview

The LP873345RHDT is a high-performance power management IC (PMIC) from Texas Instruments, designed to meet the demanding power requirements of modern processors, FPGAs, and SoCs. It integrates two step-down DC/DC converters and one low-dropout regulator (LDO) in a compact 28-pin VQFN (5x5 mm) package. The device operates over a wide input voltage range of 2.5V to 5.5V, making it suitable for battery-powered and industrial applications. With programmable output voltages via I2C interface, dynamic voltage scaling (DVS), and high efficiency up to 95%, the LP873345RHDT provides a flexible and efficient power solution.
