Classification: CPC H  Y | IPC H

Claim 5:
6. The controller of claim 5, wherein the buck control circuit generates the first PWM signal to turn on the upper power switch to cause the first phase current to flow from the input voltage to the inductor and to turn on the lower power switch to deliver the stored energy in the inductor to the output capacitor, thereby generating the regulated output voltage having the first voltage value; and wherein the boost control circuit generates the second PWM signal to turn on the lower power switch to cause the second phase current to flow from the output voltage to the inductor and to turn on the upper power switch to deliver the stored energy in the inductor to the input node, thereby returning the stored charge in the output capacitor to the input node.
