Abstract:
An example method includes controlling a switching order of a plurality of power switches. The power switches are coupled to a flying capacitor and include parasitic bipolar transistors susceptible to the voltage overstress in response to excess stray inductance of the flying capacitor. The method further includes, in response to the controlled switching order, converting an input voltage of a first voltage level to an output voltage of a second voltage level while mitigating the voltage overstress of the parasitic bipolar transistors of the plurality of power switches.
