ABSTRACT:
A voltage regulator illustrating one embodiment of the apparatus of the present invention is described. The voltage regulator includes an output stage for providing a primary output voltage on a primary output terminal and a secondary output voltage on a secondary output terminal, a switch for charging the output stage, a switch for discharging the output stage, and a controller for controlling the charging and discharging of the output stage to maintain the stability of the output voltages. The output stage includes a transformer for generating the primary and secondary output voltages, a switch for regulating the secondary output voltage, and capacitors for storing charge to maintain the primary and secondary output voltages. The transformer includes a primary inductor for generating the primary output voltage and a secondary inductor for generating the secondary output voltage. Based on feedback signals from the primary and secondary output voltages terminals, the controller generates three output signals, each output signal controlling one of the three switches.
