Abstract:
A buck-boost charge pump includes a flying capacitor and a switch network. The switch network couples an input terminal to a first terminal of the flying capacitor using a first double switch and the second terminal of the flying capacitor to a power supply voltage terminal using a second switch in a charging phase of a boost mode, the input terminal to the second terminal of the flying capacitor using a third switch and the first terminal of the flying capacitor to an output terminal using the fourth switch in both a discharging phase of the boost mode and a charging phase of a buck mode, and the power supply voltage terminal to the first terminal of the flying capacitor using a first switch and the second terminal of the flying capacitor to the output terminal using a second double switch in a discharging phase of the buck mode.

Claim (Index 9):
A buck-boost charge pump, comprising:\n a first switch having a first source-drain terminal connected to a power supply voltage terminal, a control electrode, and a second source-drain terminal, and having a corresponding body diode having an anode coupled to said first source-drain terminal, and a cathode coupled to said second source-drain terminal; a flying capacitor having a first terminal coupled to said second source-drain terminal of said first switch, and a second terminal; a second switch having a first source-drain terminal connected to said second terminal of said flying capacitor, a control electrode, and a second source-drain terminal coupled to said power supply voltage terminal, and having a corresponding body diode having an anode coupled to said second source-drain terminal, and a cathode coupled to said first source-drain terminal; a first double switch comprising first and second transistors with back-to-back body diodes between an input terminal that receives an input voltage, and said first terminal of said flying capacitor; a third switch between an input terminal and said second terminal of said flying capacitor; a fourth switch between said first terminal of said flying capacitor and an output terminal that provides an output voltage; and a second double switch comprising first and second transistors with back-to-back body diodes between said second terminal of said flying capacitor and said output terminal,. wherein said buck-boost charge pump makes both said first and second transistors of said first double switch conductive in a charging phase of a boost mode, and both said first and second transistors of said second double switch conductive in a discharging phase of a buck mode.
