Abstract: A system and method of wireless power transfer using a power converter with a bypass mode includes a power converter. The power converter includes a pulsed switch, a capacitor configured to supply a drive voltage to the pulsed switch, a first circuit configured to charge the capacitor when the power converter operates in a switched mode of operation, and, a second circuit configured to charge the capacitor when the power converter operates in a bypass mode of operation.

Abstract: A system and method of over-voltage protection includes a switch coupled between a power source and a load, a detection circuit configured to detect an onset of an over-voltage event at the load; and a driver circuit coupled to the switch and the detection circuit. The driver circuit includes a boost sub-circuit that provides a low-resistance path for opening the switch in a boost mode, the boost mode being triggered by the onset of the over-voltage event and having a predetermined duration and a steady state sub-circuit that provides a high-resistance path for holding the switch open during steady state operation when the boost mode.

Abstract: A peak current protection circuit includes a current sensing circuit configured to sense an operating current of a DC-DC converter, and an over-current detector operably coupled with the current sensing circuit. The over-current detector is configured to generate an over-current detect signal at a peak current limit that is that is independent of a voltage level of an output signal of the DC-DC converter. A method for providing over-current protection for a DC-DC converter includes sensing an operating current of a DC-DC converter at a first input of a comparator, sensing a reference current at a second input of the comparator, comparing the first input with the second input, and generating an over-current detect signal in response to the comparison such that a peak current limit for the DC-DC converter is independent of a voltage level of an output signal of the DC-DC converter.
