Abstract:
A switch control circuit includes a processor computing an on-time ratio based on an input voltage value, a first output voltage value, and a second output voltage value. The processor further computes an on-time sum based, on an output current value, an inductance value, the input voltage value, the first output voltage value and the second output voltage value, and further computes an operation frequency value that corresponds to the on-time sum. The processor further computes on-time values of a boost mode and a buck-boost mode based on the on-time sum and the on-time ratio. The processor controls a signal generator based on the operation frequency value, the on-time value of the boost mode and the on-time value of the buck-boost mode.
