PRODUCTION DATA.
It is important to set the output current limit of your input supply to an appropriate value to avoid delays in your converter analysis and optimization. If not set high enough, current limit can be tripped during start-up or when your converter output power is increased, causing a foldback or shutdown condition. It is a common oversight when powering up a converter for the first time.
