Figure 25. “Basic” Configuration (No Use of the Auxiliary Operational Amplifier)
The input voltage (V IN ) is rectified and a portion of the resulting signal is applied to the UVP pin so that the NCP4331 stops
operating when V IN is too low. The low and high thresholds of the UVP comparator set the V IN limits (V IN rising and falling)
together with the V CC capacitor.
