A temperature compensation circuit is used in a peak current control multi-phased DC/DC converter, the temperature for each phase in the converter being sensed (72) to generate corresponding first signals (Tcomp) for all the phases. The first signals are averaged to generate a second signal (Tavg) corresponding to the average temperature of all the phases and for each phase, a third signal (TCC) is generated corresponding to the difference between the first signal and the second signal. The third signal is then used to adjust the duty cycle of each phase to control the temperature of each phase to be substantially equal to the average temperature. In the steady state, the output voltage of the converter is a desired regulated voltage and the temperatures of the phases are balanced. |
