LM5121 - Wide Input Synchronous Boost Controller

General Description

The LM5121 is a synchronous boost controller intended for high-efficiency, high-power boost regulator applications.

The control method is based upon peak current mode control.

Current mode control provides inherent line feed-forward, cycle-bycycle current limiting and ease of loop compensation.
