Abstract
A charge pump controller provides the timing and drive voltages necessary for an self-regulated charge pump voltage converter. The controller utilizes a conventional non-overlapping two-phase clock to control the timing of switch drivers which control an array of switches. Pump and reservoir capacitors are distributed within the array. One of the switch drivers produces a modulated, or linear, drive voltage for one of the switches in the array in response to the charge pump's output voltage. The controller thereby produces a regulated output voltage from the charge pump.
