Abstract
A buck boost voltage converter circuit has a capacitor pump circuit for boosting an input voltage in a first mode of operation when an input voltage is below a desired voltage level. A buck converter circuit provides the output voltage responsive to the boosted input voltage from the capacitor pump circuit in the first mode of operation and provides the output voltage responsive to the input voltage in a second mode of operation when the input voltage is above the desired voltage level.
