1. A method for improving transient response in DC/DC converter circuits, the method comprising:
in response to determining that a buck-boost circuit operates in a buck mode, adjusting a compensation circuit of the buck-boost circuit to operate at a first bandwidth; and
in response to determining that the buck-boost circuit operates in a boost mode, adjusting the compensation circuit to decrease a boost mode crossover frequency and operate the buck-boost circuit at a second bandwidth that is lower than the first bandwidth.
