Abstract: 24V 10A SMPS circuit diagram . The FAN7556 is able to use the feedback pin for ON/OFF control by placing NPN transistor between the cathode of the KA431 and ground as shown in figure 12. When the transistor turns on, the current flows through the photo diode and saturates the photo transistor. As a result, the feedback voltage is dropped , IF/B) × 3k [V] where IF/B is the current flowing through the photo transistor. The VF/B is compared , 0.9V and 2.7V during the normal operation.
