ABSTRACT:
A boost hysteretic DC-DC converter is provided. The converter includes a power switch, a hysteretic comparator, an inductor, an output capacitor, and a resistive device. The resistive device is coupled to the bottom of the output capacitor, so that the output voltage is equal to the sum of the capacitor voltage and the voltage across the resistive device. The resistance of the resistance device is sufficiently large that the output voltage ripple is in phase with the inductor current.
