Abstract
A power supply including a converter, a capacitance, and a hiccup control module. The converter converts an input voltage to both an output voltage and a preliminary standby voltage when in its active state. The capacitance stores the preliminary standby voltage which is charged to an upper voltage level when the converter is in its active state and which is discharged to a lower voltage level when the converter is in its inactive state. During the standby mode, the hiccup control module operates the converter in hiccup mode by toggling between placing the converter into its inactive state when the preliminary standby voltage is charged to the upper voltage level and placing the converter into its active state when the preliminary standby voltage is discharged to the lower voltage level. The hiccup mode of the power supply eliminates a need for a separate standby converter.
