ABSTRACT:
A modulator for providing control pulses on a pulse control signal for controlling operation of a DC-DC converter is disclosed which includes a comparator, pulse control logic, a memory circuit and a switch circuit. The comparator compares a timing waveform with a compensation signal and provides a comparison signal with preliminary pulses. The pulse logic circuit receives the comparison signal and provides normal pulses on a normal pulse signal. The pulse logic circuit selects only those preliminary pulses which are provided during a permissible time window of each period of the periodic timing waveform. The memory circuit provides a pulse indication whenever a normal pulse does not occur on the pulse signal during any switching period. The switch circuit selects between the normal pulse signal and the comparison signal based on the pulse indication for providing the control pulses.
