LM5119PSQX/NOPB TI Dual Synchronous Buck Controller | 32-WQFN (5x5) | 4.5V-65V Input, 180° Phase Shift

Product Overview

The LM5119PSQX/NOPB is a dual synchronous buck controller from Texas Instruments, designed for high-voltage step-down DC-DC conversion. It operates from an input voltage range of 4.5V to 65V, making it suitable for automotive, industrial, and telecom applications. The device features two independent buck regulator channels with 180° phase shift to reduce input ripple and component stress. Each channel can deliver up to 20A of output current with excellent line and load regulation. The controller integrates high-side and low-side gate drivers, bootstrap diode, and programmable soft-start. It is available in a compact 32-pin WQFN (5x5 mm) package.
