2 A in a 2x3 mm QFN — the power-density play
The TPS62148RGXR delivers 2 A continuous output from a 11-VFQFN-HR package measuring 2x3 mm — that is the smallest footprint in TI's 2 A DCS-Control family. The 2.5 MHz switching frequency lets you drop the inductor down to the 1 µH range and use a 10 µF ceramic output cap, keeping the total solution area under 20 mm².
Input range and output flexibility
Input voltage spans 3 V to 17 V, covering 5 V and 12 V rails with margin. The adjustable output sits between 0.8 V and 12 V, so it handles 1.2 V core rails, 3.3 V I/O, and 5 V peripheral supplies from the same BOM. Synchronous rectification is built in — no external Schottky diode needed.
No official second source or pin-compatible alternate is published — this is a single-sourced TI part. For production BOMs, the 11-VFQFN-HR footprint is unique to this series; no cross-reference exists in the TPS6214x family.
