A controller for a Buck-Boost converter includes a feedback control circuit responsive to the converter output and configured to generate a control signal for the Buck switch and a feed forward control circuit responsive to the input voltage and configured to generate a control signal for the Boost switch. The feed forward circuit is decoupled from the converter output and may be programmable to select a predetermined output voltage.
