More Information
The LM5141 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 features slew rate control to simplify the compliance with EMI requirements.
