LM5122ZA - Wide-Input Synchronous Boost Controller

The LM5122ZA is a multi-phase capable synchronous boost controller intended for highefficiency synchronous boost regulator applications.

The control method is based upon peak-current-mode control.

Current-mode control provides inherent line feed forward, cycle-by-cycle current limiting, and ease of
