1. A switch controller for charge pump tracker circuitry comprising:
first monitoring circuitry configured to monitor a first voltage across a first flying capacitor during a first discharging phase;
second monitoring circuitry configured to monitor a second voltage across a second flying capacitor during a second discharging phase; and
boost logic circuitry in communication with the first monitoring circuitry and the second monitoring circuitry, wherein the boost logic circuitry is, in response, configured to control a first switch network coupled to the first flying capacitor and a second switch network coupled to the second flying capacitor so that the first discharging phase and the second discharging phase alternate in an interleaved mode, and so that the first discharging phase and the second discharging phase are in phase during a parallel boost mode.
