We are considering using LMZM33603 for an application with 24V input, 15V output @1.8A. I notice in the datasheet it specifies up to 18V output @2A and up to 13.5V output up to @3A. Is this current range for sustained DC current? Would there be any concern for this application if there was a large load step to 1.8A? If an application is regulating to 15V output (or other voltage greater than 13.5V) and the current exceeds 2A, what is the response?
