4.1 1.0 MHz and 2.5 MHz Switching Frequencies

The TPS629xx-Q1 switching frequency can be set to 1.0 MHz or 2.5 MHz using the smart configuration pin. This allows the user to flexibly set the switching frequency to suit their application needs. To improve the efficiency and reduce switching losses of the converter, 1.0 MHz can be selected, with the trade-off of using a larger inductor. This selection is ideal for applications that may not have large space constrains, but efficiency or thermals are the main concern. For applications needing a smaller inductor, optimized overall solution size, and can afford a slight drop in efficiency, 2.5 MHz is the ideal choice.
