, 20 k, 10 k
The first step in the design procedure is to verify whether the maximum possible output current of the buck-boost
converter supports the specific application requirements. To simplify the calculation, the fastest approach is to
estimate converter efficiency by taking the efficiency numbers from the provided efficiency curves or to use a
worst case assumption for the expected efficiency, e.g., 80%. The calculation must be performed for the
minimum assumed input voltage where the peak switch current is the highest. The inductor and external
Schottky diode have to be able to handle this current.
With,
Iswpeak = Converter peak switch current (minimum switch current limit = 1.1A)
fs = Converter switching frequency (typical 750 kHz)
L = Selected inductor value
η = Estimated converter efficiency (use the number from the efficiency curves or 0.8 as an assumption)
