Abstract
The present disclosure provides for a processing element configured to couple to a first ramp generator and a second ramp generator and control the first ramp generator while a power converter is operating in a buck-boost mode of operation to generate a first ramp signal beginning at a first value and increasing to a second value during a first clock cycle and generate the first ramp signal beginning at the first value and increasing to a third value during a second clock cycle following the first clock cycle and control the second ramp generator while the power converter is operating in the buck-boost mode of operation to generate a second ramp signal beginning at a fourth value and decreasing to a fifth value during the first clock cycle and generate the second ramp signal beginning at the fourth value and decreasing to a sixth value during the second clock cycle.
