Abstract: According to an exemplary implementation, an integrated circuit (IC) includes a logic circuit monolithically formed on the IC. The logic circuit is configured to generate modulation signals for controlling power switches of a power inverter. The logic circuit generates the modulation signals based on at least one input value. The IC further includes a voltage level shifter monolithically formed on the IC. The voltage level shifter is configured to shift the modulation signals to a voltage level suitable for driving the power switches of the power inverter. The logic circuit can be a digital logic circuit and the input value can be a digital input value. The IC can also include a sense circuit monolithically formed on the IC. The sense circuit is configured to generate the input value.

Abstract: In one implementation, a power converter includes an output stage integrated circuit (IC) in a group III-V die including a depletion mode group III-V transistor, and a driver IC in a group IV die. The driver IC is configured to drive the output stage IC. In addition, a group IV control switch in the group IV die is cascoded with the depletion mode group III-V transistor. The power converter further includes an overcurrent protection circuit for the depletion mode group III-V transistor, the overcurrent protection circuit monolithically integrated in the group IV die.
