The 2.05 V minimum input covers a single-cell Li-Ion battery through its discharge curve, and the 6 V maximum handles 5 V USB or regulated 5 V rails without a pre-regulator. ## 6-UFDFN package — layout and thermal notes The 6-UFDFN package measures 1.45 mm × 1.0 mm — roughly the size of a 0402 resistor. Standard MSL-1 moisture sensitivity applies — no bake required before reflow if the shelf-life seal is intact. For new designs, this means standard lead times through distribution — no urgency to stockpile or qualify a second source. The base product number TPS622311 covers multiple fixed-output voltage variants in the same package, so if a future board spin needs a different output voltage, the PCB footprint stays the same.","metaTitle":"TPS622311DRYR Step-Down Converter, 500 mA, 2 MHz, 6-SON","metaDescription":"Texas Instruments TPS622311DRYR step-down (buck) converter, 500 mA output, 2 MHz switching, fixed 1.1 V, -40°C to 125°C, 6-UFDFN package.
