Voltage supply system with boost converter and charge pump
First Claim
1. A method for operating a voltage supply system, the method comprising:
- generating a first output voltage with a charge pump of the voltage supply system based on an input voltage when in a first mode;
delivering the input voltage as a second output voltage when in a second mode; and
generating a third output voltage with a boost converter of the voltage supply system based on the input voltage when in a third mode, the boost converter including an input node, an inductor, and one or more switches, but no switch coupled between the inductor and the input node.

Abstract
Voltage supply system with boost converter and charge pump. A voltage supply system can include a boost converter controllable to receive an input voltage at an input node and generate an output voltage when the output voltage is greater than or equal to the input voltage. The voltage supply system can include a charge pump controllable to receive the input voltage at the input node and generate the output voltage when the output voltage is less than the input voltage. The voltage supply system can further include a controller configured to receive a control signal and control the boost converter or the charge pump to generate the output voltage at an output node based on the control signal.
