Abstract:
A switching power supply includes a power switch, an adjusting circuit and a limit signal generator. The power switch operates according to a switch control signal. The adjusting circuit adjusts the turn-on time of the switch control signal according to a limit signal and a detecting signal which corresponds to the current passing the power switch. When the detecting signal exceeds or is equal to the limit signal, the limit signal generator samples a reference signal and updates the limit signal according to the sampled reference signal.
