The "brain" of the circuit. This IC (often a 6-pin or 8-pin surface-mount device) controls the frequency and duty cycle of the switching. Switching MOSFET:

Being a PTC, it should automatically reset once the short circuit or overcurrent condition is removed and the component cools down. If it remains "open," it must be replaced.

: Monitors the 24V output and sends a signal back to the PWM controller to adjust the duty cycle, ensuring the voltage remains stable at the rated 1.1A load. Recommended Next Steps
