decreased whenever output voltage exceeds nominal, the voltage regulation loop is closed. For example, whenever the load current increases, output voltage will decrease slightly, and sensing this, the error amplifier raises the ITH/RUN voltage by sourcing current into the ITH/RUN pin, raising the current comparatorthreshold,thus increasing the peak currents through the transformer primary and secondary. This delivers more current to the load, bring- ing the output voltage back up.
