Abstract:
A voltage regulation (VR) module of an Information Handling System (IHS) operates a switching direct current to direct current (DC-DC) voltage regulation (VR) power circuit in a constant current mode at a constant current level. The VR module approximates the capacitance value of the output capacitive load at the output terminal of the switching DC-DC VR power circuit based upon a time interval for output voltage to reach a threshold. The VR module then operates the switching DC-DC power circuit in constant output voltage mode using one group of VR operating settings to optimize performance for the capacitance value of the output capacitive load.
