Abstract
A control circuit and method, wherein an error signal is generated representative of a difference between an output voltage of a switching circuit and a nominal signal; a single control signal is generated, representative of an average error of the error signal; the single control signal is compared with a first periodic reference signal and a second periodic reference signal; a first pulse width modulated signal is generated by a Buck modulator; and a second pulse width modulated signal is generated by a Boost modulator. The maximum value of the first periodic reference signal and the minimum value of the second periodic reference signal are higher and lower, respectively, than the single control signal in a transient control mode between a Buck control mode and a Boost control mode.
