... Error Flag Operation The Error Flag pin on the NCP5661 will produce a logic Low when it drops below the nominal output voltage. Refer to the electrical characteristics for the threshold values at which point the Error Flag goes Low. When the NCP5661 is above the nominal output voltage, the Error Flag will remain at logic High ...
