A conductive liquid path detection circuit for detecting a conductive liquid present in a receptacle connector and/or a mating connector plug is configured for discharging an electron charge from any conductive liquid present on a connector pin in the receptacle connector and/or a mating connector plug. The conductive liquid path detection circuit charges any conductive liquid present on the connector pin with an electron charge. The circuit repeatedly samples and retains the samples of the measurements of a voltage level present at the connector pin. The conductive liquid path detection circuit then analyzes the samples of the measurements to determine a slope of the samples of the measurements of a voltage level over time; and determines when an amplitude of a final measurement of the voltage level is less than a conductive liquid detection threshold level.

A multi-phase DC-to-DC converter is configured to achieve fast transient response and to optimize efficiency over the load range. Phase shedding changes the active number of phases according to output currents. Each phase of the converter has an inductor configured to optimize the efficiency for a range of load currents in which that phase is used. A converter may have 3 phases, the first used only in sleep mode and has a large inductance with low AC losses, the second used in sync mode at low currents and having a lower inductance with low AC losses, the third phase is used in sync mode at high currents and has small inductance with low DC losses. The number of phases is &#x2267;2.
