Abstract:
1. An apparatus comprising: a power converter configured to generate a feedback current based on a pulse modulated waveform signal; a pulse modulated waveform generator configured to generate the pulse modulated waveform signal; a comparator configured to receive a peak current reference signal and the feedback current, and the comparator configured to generate an output signal for controlling the pulse modulated waveform generator based on the peak current reference signal and the feedback current; a blanking circuitry interposed between the comparator and the pulse modulated waveform generator, configured to prevent the output signal from reaching the pulse modulated waveform generator starting at a blanking time and for a blanking time period; and a controller coupled with the blanking circuitry, the controller configured to adjust the blanking time and the blanking time period based on an operating condition and a system parameter of the apparatus.
