Abstract:
1. A switching power supply circuit comprising: sub-circuits comprising: a capacitor/inverter circuit comprising an inverter, a switch, and a capacitor connected to an input of said inverter and said switch, said switch being operative to allow a voltage to be stored on said capacitor, said voltage being indicative of said regulated output voltage, said inverter comprising a signal output, said signal output providing an out of regulation signal when a difference between said voltage and said regulated voltage is sensed and said switch is inoperative; and a standby control circuit comprising disabling circuits, said disabling circuits disabling said sub-circuits when said logical low signal is detected permitting the switching power supply circuit to operate at a minimum current, a switch control circuit controlling at least said switch, said switch control circuit controlling said switch to be inoperative when said logical low signal is detected, and enabling circuits, said enabling circuits re-enabling said sub-circuits when said out of regulation signal is detected allowing the switching power supply to provide said regulated output.
