Abstract:
A hysteretic DC-DC converter includes a reference circuit, a hysteretic comparator, and a control circuit. The hysteretic comparator may be configured to compare a monitored output of the converter to a reference signal generated by the reference circuit and to compare a load ground of the output of the converter to a reference signal ground of the reference signal. The hysteretic comparator may perform the aforementioned comparisons simultaneously. The hysteretic comparator may generate a comparator output based on the comparison of the output of the converter to the reference signal and the comparison of the load ground to the reference signal ground. The control circuit may vary a control output to increase or decrease the output of the converter based on the comparator output.
