Abstract
Various embodiments relate to a buck-boost converter controller configured to control a buck-boost controller, wherein the buck-boost converter has a buck mode of operation, a boost mode of operation, and a buck-boost mode of operation, including: a phase controller configured to produce phase control signals to control switching in the buck-boost converter, wherein the phase control signals are based on a mode of operation of the buck-boost converter; and an automatic mode selector configured to indicate to the phase controller the mode of operation of the buck-boost controller based upon a buck on-time TON_bk or a buck off-time TOFF_bk, a boost on-time TON_bst or a boost off-time TOFF_bst, and a control configuration on-time TPI3, where TON_bk is the on-time during the buck mode of operation, TOFF_bk is the off-time during the buck mode operation, TON_bst is the on-time during the boost mode of operation, TOFF_bk is the off-time during the boost mode operation, and TPI3 is the time where a second high-side transistor is on and a first low side transistor is on.
