Abstract
Systems and methods for driving a low quiescent current DCDC converter are disclosed. An error threshold compensation circuit of the DCDC converter is configured to detect an output voltage of the DCDC converter, compare the output voltage to a target voltage, and modify a first threshold voltage of the hysteresis control circuit based on the comparison.
