LM25141/LM25141-Q1 Synchronous Buck Controllers

Texas Instruments LM25141/LM25141-Q1 Synchronous Buck Controllers are intended for high voltage wide VIN step-down converter applications. The control method is peak current mode control. Current mode control provides inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation. The LM25141 features slew rate control to simplify compliance with CISPR and Automotive EMI requirements.
