Classification: CPC G  H | IPC G  H

Claim 5:
6. The apparatus of claim 2, wherein the one or more control circuits are configured to:
operate the charge pump in a first configuration having parallel pump stages during a first period of time as the output voltage is ramped;
operate the charge pump in a second configuration having series pump stages during a second period of time as the output voltage is ramped;
modify the target duty cycle based on a first mapping of output voltage to target duty cycle when operating the charge pump in the first configuration during the first period of time, wherein the first mapping is based on the first configuration; and
modify the target duty cycle based on a second mapping of output voltage to target duty cycle when operating the charge pump in the second configuration during the second period of time, wherein the second mapping is based on the second configuration.
