Equivalent & Substitute Parts Reference for LM5041AMTC

Part Overview

The LM5041AMTC is a Power Management Integrated Circuit (PMIC) DC-DC controller from Texas Instruments. It features half-bridge and push-pull topologies for positive output step-up and step-down regulation. The device incorporates an integrated transistor driver, synchronous rectifier, and control features such as dead time, frequency control, and soft start. The LM5041AMTC is packaged in a 16-TSSOP case and is designed for surface mount applications. Its part status is listed as obsolete, which requires the identification of parametric equivalent substitute models to maintain supply continuity and design compatibility.
