Abstract

One embodiment of the present invention includes a power supply system. The power supply system comprises a variable voltage source configured to provide and incrementally increase a control voltage associated with a pass-transistor. The power supply system also comprises an inrush current monitor configured to monitor a current-flow through the pass-transistor. The power supply system further comprises a voltage control circuit configured to halt the incremental increase of the control voltage in response to the current-flow exceeding a predetermined current limit.
