ABSTRACT:
The present invention is a spike converter providing a special mode of operation of a low power fly-back converter in a very narrow duty cycle range in particular. This spike operation minimizes the size of the required reactive components such as that of the power transformer and output capacitance. The present invention automatically achieves low idle power consumption due to the nature of the feedback under fixed, narrow duty cycle or spike operation. The spike operation is defined by the lower limit of the on time of the switching element being generated by the sum of the propagation delays of a current sense comparator and an off time pulse generating comparator.
