Abstract

Presented are systems and methods for improving transient response in buck-boost circuits avoid circuit instabilities in both boost mode and buck mode. In embodiments, this is accomplished when, in response to determining that the circuit operates in buck mode, a compensation circuit is adjusted to operate at a first bandwidth. In response to determining that the circuit operates in boost mode, the compensation circuit may then be adjusted to decrease a boost mode crossover frequency and operate at a second, lower bandwidth.
