ABSTRACT:
A discontinuous, free-running flyback power supply with precise, predictable switching control is provided. An open collector comparator provides a digital signal to the control switching transistor for precise control of the switching action of the power switching transistor. This digital signal also provides a minimum hold-off time for the power switching transistor for power-up and low load conditions.
