3 MHz switching — inductor and BOM fit
The TPS622318DRYT is a synchronous step-down converter from Texas Instruments that switches at 3 MHz, letting the designer use a small inductor — typically in the 1 µH to 2.2 µH range — which saves board area in space-constrained portable or industrial modules. 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.
