4 Summary

This application report presents how to calculate inductor and output capacitance and how they affect loop stability about TPS563202. It also gives a typical rule to select inductor and output capacitance. It is recommended to put double pole before internal zero frequency. To be safer please follow recommended LC table. The zero frequency of the SOT563 package parts in Table 1-1 is 24kHz.
