Abstract
A buck-boost converter comprises generating a first ramp using a first current source having a current level proportional to an input voltage of a buck-boost converter, and a second ramp using a second current source having a current level proportional to an output voltage of the buck-boost converter, generating a first threshold voltage proportional to a difference between the input voltage and the output voltage of the buck-boost converter, and a second threshold voltage proportional to the input voltage of the buck-boost converter, terminating a gate drive signal of a first low-side switch of the buck-boost converter based upon comparing the first threshold voltage and the first ramp, and terminating a gate drive signal of a second high-side switch of the buck-boost converter based upon comparing the second threshold voltage and the second ramp.
