Abstract
An adaptive phase offset controller for use with a switching power converter having first and second channels. The controller includes a discriminator which detects a 'critical condition' in which a switching signal for the first channel transitions during a critical time interval so as to give rise to crosstalk that can corrupt the operation of the second channel's control circuit. When the discriminator detects a critical condition, a phase offset circuit offsets the phase of the first channel's switching signals, such that subsequent transitions occur outside of the critical time interval. A second discriminator and phase offset circuit are preferably employed to detect critical conditions which can give rise to crosstalk that can corrupt the operation of the first channel's control circuit.
