LM25141-Q1 - Wide Input Range Synchronous Buck Controller

Datasheet Summary

Description

The LM25141-Q1 is a synchronous buck controller, intended for high-voltage, wide-VIN, step-down regulator 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.
