Abstract
A switching power converter is provided with a phase-shifting RC network for phase-shifting a divided version of a drain voltage of a power switch transistor into a phase-shifted voltage. A comparator compares the phase-shifted voltage to a DC bias voltage to detect peaks and valleys during resonant oscillations of the drain voltage of the power switch transistor.
