Abstract
Apparatus for providing over-current protection in a power converter device includes a first circuit for providing high-side sinking over-current protection for the power converter device responsive to a phase signal and a high-side over-current signal of the power converter device. A second circuit provides low-side sinking over-current protection for the power converter device responsive to the phase signal and the low-side over-current signal of the power converter device. Finally, a third circuit provides low-side sourcing over-current protection responsive to the phase signal, the low-side over-current protection signal and a power ground signal of the power converter device.
