A level-shift circuit for use with a half bridge in accordance with an
embodiment of the present application includes an oscillator operable to
provide a timing signal, a level-shift switch controlled by the timing
signal of the oscillator, a high side control circuit operable to provide
a high side control signal to a high side switch of the half bridge to
control the high side switch and a low side control circuit operable to
provide a low side control signal to a low side switch of the half bridge
to control the low side switch. The level-shift switch is turned ON when
the timing signal is high such that the level-shift switch connects the
high side control circuit to ground and the high side control signal
stays low to keep the high side switch OFF when the timing signal is
high. The low side control circuit provides the low side control signal
to turn the low side switch ON a predetermined period of time after the
timing signal goes high.
