Abstract
A power switcher includes a first normally-off transistor that switches between interrupting and not interrupting a current path between first and second electrodes according to a drive voltage input to a first control electrode, a second normally-on transistor cascode-connected to the first transistor and including a second control electrode to which the second electrode of the first transistor is connected, a control voltage generator that generates a control voltage in accordance with a voltage between the first and second electrodes of the first transistor, and a drive voltage generator that generates a drive voltage equal to or lower than a withstand voltage of the first transistor in accordance with the control voltage.
