Power converter including integrated driver providing overcurrent protection

摘要

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.
