Abstract:
Disclosed is a charge pump system having a charge pump with 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. Also included is a first buck/boost switch having a first terminal coupled to the voltage output terminal, 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 includes a first terminal coupled to the voltage output terminal, a second terminal coupled to a second output node, and a control terminal for receiving a second control signal. Further included is a switch controller that is adapted to generate the first control signal and the second control signal such that voltage pulses output from the first output node and the second output node, respectively, are asymmetrical and coincidental.
