1. A power electronic device comprising:

  • a package having a supply terminal and a reference terminal;

    first and second drivers;

    a first electronic switch and a second electronic switch being integrated on said package, each of said first and second electronic switches having a first conduction terminal, a second conduction terminal, and a control terminal, the first conduction terminal of said first electronic switch being coupled with the supply terminal, and the second conduction terminal of said second electronic switch being coupled with the reference terminal, control terminals of said first and second electronic switches being coupled to respective ones of said first and second drivers;

    at least one resistive member coupled between the second conduction terminal of said first electronic switch and the first conduction terminal of said second electronic switch to allow a bidirectional flow of current therebetween;

    said package comprising a first terminal coupled to the second conduction terminal of the first electronic switch, a second terminal coupled to the first conduction terminal of said second electronic switch, and an output terminal;

    a first inductance coupled between the first terminal and said output terminal;

    a second inductance coupled between the second terminal and the output terminal; and

    said package comprising at least one of a wafer-level package and a chip-scale package, with said package configured to be directly coupled to a printed circuit board so as to eliminate bonding wires and reduce parasitic inductance.
