LP87334ERHDR TI Power Management IC | 28-VQFN (5x5) | Dual Buck, LDO

Product Overview

The LP87334ERHDR from Texas Instruments is a high-performance power management IC (PMIC) designed for space-constrained applications. Housed in a compact 28-pin VQFN (5x5 mm) package, it integrates dual step-down DC/DC converters and two low-dropout (LDO) regulators, providing a complete power solution for processors, FPGAs, and other digital loads. With input voltage range from 2.5V to 5.5V, it supports single-cell Li-ion battery or 3.3V/5V rail inputs. The device features I2C-compatible interface for dynamic voltage scaling and configuration, making it ideal for portable and embedded systems.
