Abstract:
A buck-boost converter comprises a first high-side switch and a first low-side switch connected in series between an input voltage terminal and ground, a second high-side switch and a second low-side switch connected in series between an output voltage terminal and ground, an inductor connected to a common node of the first high-side switch and the first low-side switch, and a common node of the second high-side switch and the second low-side switch and a control apparatus configured to generate gate drive signals, wherein the control apparatus comprises a first timer for setting a turn-off time of the first low-side switch, a second timer for setting a turn-off time of the second high-side switch and a peak current mode control device for setting a turn-off time of the first high-side switch and a turn-off time of the second low-side switch.

Claim (Index 1):
An apparatus comprising:\n a first timer configured to determine a turn-off edge of a gate drive signal applied to a low-side switch of a buck converter portion of a buck-boost converter, wherein the first timer comprises a first input configured to receive a first ramp, a second input configured to receive a first threshold voltage, and wherein the first ramp is generated by a first current source having a current level proportional to an input voltage of the buck-boost converter, and the first threshold voltage is proportional to a difference between the input voltage of the buck-boost converter and an output voltage of the buck-boost converter; and a second timer configured to determine a turn-off edge of a gate drive signal applied to a high-side switch of a boost converter portion of the buck-boost converter, wherein the second timer comprises a first input configured to receive a second ramp, a second input configured to receive a second threshold voltage, and wherein the second ramp is generated by a second current source having a current level proportional to the output voltage of the buck-boost converter, and the second threshold voltage is proportional to the input voltage of the buck-boost converter.
