Abstract
A hysteretic power converter constituted of: a switched mode power supply; a hysteretic comparator, a first input of the comparator arranged to receive a feedback signal providing a representation of the output voltage of the switched mode power supply and a second input of the comparator arranged to receive a reference voltage; a ramp capacitor coupled to one of the first and second input of the comparator; a current source, a terminal of the current source coupled to the ramp capacitor and arranged to drive current to the ramp capacitor; and a switchable current source, a terminal of the switchable current source coupled to the ramp capacitor, the switchable current source arranged to drive current to the ramp capacitor in a direction opposite the current driven by the current source, wherein the switchable current source is alternately enabled and disabled responsive to the output of the hysteretic comparator.
