Abstract:
1. A multiple output charge pump comprising: a first flying capacitor having a positive electrode and a negative electrode; a second flying capacitor having a positive electrode and a negative electrode; a first output node to provide a first voltage having a first polarity to a first output capacitor; a second output node, distinct from the first output node, to provide a second voltage different than the first voltage to a second output capacitor, the second voltage having the first polarity; a third output node, distinct from the first output node and the second output node, to provide a third voltage different than the first voltage and the second voltage to a third output capacitor, the third voltage having a second polarity opposite the first polarity; and a switching network configured to provide a first mode where the first and second flying capacitors are connected in series or in parallel between an input voltage (VIN) and ground, a second mode where the first and second flying capacitors are connected in series, and a third mode.
