A direct current to direct current converter includes first and second
switches to output voltages on first and second output terminals in
response to appropriate turn-on voltages at first and second control
terminals. The first control terminal may selectively communicate with
one of N>2 different voltages. The converter may include a first
multi-level controller in communication with the first control terminal,
the controller including N drivers to selectively apply the N>2
different voltages to the first control terminal.
