ABSTRACT:
A high frequency miniaturized switching power supply has a unidirectional spike filter which removes spikes appearing on a feedback signal before such feedback signal is provided to the comparator of the switching power supply. The spike filter removes voltage spikes of one polarity without lengthening the reset time of the comparator in response to a wavefront of the opposite polarity.
