Abstract
In one embodiment, a capacitor of a charge pump circuit is referenced to a high side voltage or top voltage rail.
Claims19
A method of forming a floating charge pump comprising:
- referencing an output capacitor of the floating charge pump to a high side voltage.
A floating charge pump circuit comprising:
- an first input coupled to receive an input voltage;
- and
- an output capacitor referenced to the input voltage.
A method of forming a charge pump controller comprising:
- forming a first input operable for receiving a feedback signal representative of an internal regulated voltage of the charge pump controller;
- and
- coupling the charge pump controller to disable generating a charge pump signal when the internal regulated voltage exceeds a protection value of the charge pump controller.
