LM25117PMH/NOPB TI DC-DC Controller | 20-HTSSOP | Wide Vin 4.5-42V, 1% Accuracy

Product Overview

The LM25117PMH/NOPB is a wide input voltage range synchronous buck controller from Texas Instruments, designed for high-efficiency step-down DC-DC conversion. It operates from 4.5V to 42V and provides a regulated output voltage with ±1% accuracy over line, load, and temperature. The device features adaptive dead-time control, frequency synchronization, and a programmable soft-start. Housed in a 20-pin HTSSOP package with exposed pad for thermal dissipation, it is suitable for industrial, automotive, and telecom applications.
