More Information

The LM5141-Q1 is a synchronous buck controller, 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 LM5141-Q1 features slew rate control to simplify the compliance with CISPR and automotive EMI requirements.
