The fixed 1.25 V output eliminates the external feedback divider, reducing BOM count and placement risk. ## Input range and thermal envelope Input voltage spans 2.05 V to 6 V, covering single-cell Li-Ion down to near-depletion and regulated 5 V rails.","metaTitle":"TI TPS622318DRYT Step-Down Converter, 3 MHz, 500 mA, 6-UFDFN","metaDescription":"Texas Instruments TPS622318DRYT synchronous buck converter, 3 MHz switching frequency, 500 mA output, fixed 1.25 V.
