Small-package buck for tight boards
The TPS62623YFFT is a 600 mA step-down (buck) regulator with a fixed 1.225 V output, switching at 6 MHz to keep the inductor and capacitors small. The 6-DSBGA package (0.9 mm × 1.3 mm typical) is a 6-ball wafer-level chip-scale package — no leads, no exposed pad — so the board footprint is essentially the part outline plus a few vias.
6 MHz switching shrinks the passive budget
At 6 MHz, the inductor value drops to the 0.47 µH to 1 µH range and output capacitors to 4.7 µF or less — a real advantage when board area is measured in square millimeters.
Active production, no end-of-life watch needed
Input range and output tolerance
Input voltage range is 2.3 V to 5.5 V, covering single-cell Li-ion, 3.3 V or 5 V rails. The fixed output is 1.225 V — no feedback divider needed, which saves two resistors and a feedback-node noise pickup path.
