Patent ID: 8624576

Claim:
A charge pump system comprising: a charge pump having a switch control input, a voltage output terminal, a high voltage terminal coupled to a high voltage node and a low voltage terminal coupled to a low voltage node; a first buck/boost switch having a first terminal directly coupled to the voltage output terminal of the charge pump, a second terminal coupled to a first output node and a first control terminal for receiving a first control signal; a second buck/boost switch having a first terminal directly coupled to the voltage output terminal of the charge pump, a second terminal coupled to a second output node, and a control terminal for receiving a second control signal; and a switch controller having an output coupled to the switch control input of the charge pump, the switch controller being adapted to generate the first control signal, and the second control signal such that a first voltage pulse output from the first output node and a second voltage pulse output from the second output node are asymmetrical and coincidental.
