At this switching speed, the converter operates above the audible band, so there is no transformer whine in audio or sensor applications. ## 10-SON exposed pad — thermal and layout checklist","metaTitle":"TPS63031DSKR Buck-Boost Converter, 2.4 MHz, 900 mA Switch","metaDescription":"TI TPS63031DSKR step-up/step-down buck-boost converter, fixed 3.3 V output, 900 mA switch, 2.4 MHz, 10-SON.
