Classification: CPC G  H | IPC G

Claim 10:
11. A apparatus comprising:
a ramp-down compensator operable to generate a ramp down compensation voltage based at least partially on a valley current sense voltage and an inductor voltage of an inductor at an inductor node, and to apply the ramp down compensation voltage to the inductor node; and
a ramp-up compensator including a system capacitor operatively coupled at a first terminal to the inductor node and at a second terminal to a reference voltage, the ramp-up compensator operatively coupled to the ramp-down compensator, and operable to, in accordance with a first determination that the valley current sense voltage and the inductor voltage are not equal, apply a control signal to the system capacitor, and, in response to the application of the control signal, modify a predetermined capacitance of the system capacitor to a first modified capacitance.
