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 2):
The apparatus of  claim 1 , further comprising:\n a first offset voltage source connected between the first input of the first timer and the first ramp, wherein the first offset voltage source is configured such that a positive voltage is applied to the first input of the first timer when the first ramp is reset; and a second offset voltage source connected between the first input of the second timer and the second ramp, wherein the second offset voltage source is configured such that a negative voltage is applied to the first input of the second timer when the second ramp is reset.
