ABSTRACT:
A switching mode power supply (SMPS) is presented to compensate for variations of maximum output power caused by variations of input power. The output power varies according to variations of input power because of a propagation delay of the SMPS. To compensate for the propagation delay, a reference voltage for turning off a switching MOS transistor is differently established depending on the input voltage. The variation of maximum output power according to the input voltage is prevented by differentiating the turned-off time of the reference voltage for turning off a main switch, such as a switching MOS transistor according to the input voltage.
