Abstract
In one embodiment, a method of controlling a converter can include: (i) when first and fourth switches are on, and second and third switches are off, generating an on time signal according to an input voltage and a stable output voltage of the converter; (ii) generating an off time signal according to the input voltage and the stable output voltage of the converter; (iii) generating a reference time voltage according to a reference current signal and a reference voltage signal; and (iv) controlling the first, second, third, and fourth switches based on whether the on time signal is activated to indicate that the converter is operating in a buck mode, the off time signal is activated to indicate that the converter is operating in a boost mode, or the reference time signal is activated to indicate that the converter is operating in a buck-boost mode.
