LM5170PHPR TI Power Management IC | 48-HTQFP (7x7) | Dual-Channel, 4.5V-55V

Product Overview

The LM5170PHPR is a dual-channel, multi-phase buck-boost controller from Texas Instruments, designed for high-efficiency power conversion in applications requiring wide input voltage range. It operates from 4.5V to 55V and can be configured as a buck, boost, or buck-boost converter. The device integrates two independent channels that can be paralleled for higher current or used for separate outputs. With programmable switching frequency up to 1MHz, it enables compact power solutions.
