  • I/O protected buck then boost or boost then buck converter, with interleaving option
    Patent number: 10680520
    Abstract: A DC/DC converter is embodied in a single integrated circuit (IC) and may comprise a book-boost converter or a buck then boost or boost then buck converter. A first protection switch is connected between a bus, or input, terminal and one side of the DC/DC converter circuit art. A second protection switch is connected between an energy storage, or output, terminal and an inductor which is coupled to another side of the DC/DC converter circuit. This IC comprises input and output protection switches for input reverse voltage protection and overvoltage protection from transients. Additionally, passive filters may be connected to an input of each protection transistor to absorb overvoltages, transients, and current inrushes. The structure may comprise a two quadrant converter. Another embodiment comprises a four-quadrant converter comprising a first and a second opposed to quadrant converter.
