For use in a switch-mode power converter including parallel-coupled first and second switches, the first switch having a temperature-dependent resistance, a circuit for, and method of, distributing current between the first and second switches. In one embodiment, the circuit includes a device having a temperature-dependent characteristic, in thermal communication with the first switch and electrically coupled to a gate of the first switch, that senses a temperature of the first switch, modulates an amplitude of a drive waveform applied to the gate based on the temperature and thereby redistributes the current.
