... Comparing the feedback voltage with the voltage across the I Rsense resistor plus an offset voltage makes it possible to sup control the switching duty cycle. When the reference pin voltage of the KA431 exceeds the internal reference voltage of 2.5V, the H11A817A LED current increases, thus pulling Da down the feedback voltage and reducing the duty cycle ...

... If Vfb exceeds 2.8V blocked and the 5uA current source starts to charge C slowly up to Vcc. In this condition, Vfb continues increasing until it reaches 7.5V, when the switching operation is terminated as shown in Figure 8. The delay time for shutdown is the time required to charge C 7 ...

... PWM comparator inverting input voltage together with the SenseFET current slowly after it starts up. The soft start time can be programmed using a capacitor on the soft- start pin. The pulse width to the power switching device is progressively increased to establish the correct working conditions for transformers, inductors, and capacitors. It also helps to prevent transformer saturation and reduce the stress on the secondary diode during startup ...
