The smart configuration pin is one of the primary contributors to the space savings and a key differentiators between the next generation devices and their predecessors. The MODE/S-CONF pin gives the user flexibility to select the settings of four features (FB/VSET, switching frequency, FPWM/PFM, and output discharge) with only one resistor. In the previous generation, each of these features would have to be configured individually. There are several advantages associated with this pin, too many to discuss in this document.
