A method of implementing a power-based current limiting circuit in an
information handling system includes providing a power supply having an
output voltage operating range that can vary between a first voltage
output level and a second voltage output level. The power supply output
voltage is coupled to a load module via a switch. A power output of the
power supply supplied to the load module is detected as a function of the
load module current and the output voltage. Lastly, the switch is
controlled between a first state and a second state in response to the
detected power output.
