LM5122ZA Description
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 loop pensation.
