Zusammenfassung:	A switching mode power supply includes a power supply, a feedback circuit, and a switching controller. The power supply includes a main switch coupled to a primary coil of a transformer and supplies power to a secondary coil of the transformer according to an operation of the main switch. The feedback circuit generates a feedback voltage corresponding to an output voltage applied to the secondary coil. The switching controller compensates a propagation delay by controlling a duty of the main switch according to a result of comparing a first signal that fluctuates according to a first voltage corresponding with a current flowing through the main switch to a reference voltage corresponding to the feedback voltage.
