LP875761ARNFRQ1 TI PMIC | 26-VQFN-HR(4.5X4) | 4 Buck Converters, 10A

Product Overview

The LP875761ARNFRQ1 is a high-performance, multi-phase step-down converter from Texas Instruments, designed for automotive and industrial applications. It integrates four synchronous buck converters capable of delivering up to 10A per phase, with a wide input voltage range of 2.8V to 5.5V. The device is housed in a compact 26-pin VQFN-HR package (4.5mm x 4mm) and features I2C/SPI interface for dynamic voltage scaling and configuration. With its high efficiency and low quiescent current, it is ideal for powering processors, FPGAs, and other core rails in space-constrained systems.
