LM5140-Q1 - Wide Input Range Dual Synchronous Buck Controller

Description

The LM5140-Q1 is a dual synchronous buck controller intended for high voltage wide VIN stepdown converter applications.

The control method is based on current mode control.

Current mode control provides inherent line feedforward, cycle-by-cycle current limiting, and easier loop compensation.

Features
