6 MHz switching — why the small inductor matters
That 6 MHz switching rate is the headline feature — it lets the designer use a sub-1 µH inductor and small ceramic capacitors, shrinking the total solution footprint to fit the 6-bump DSBGA package. For a space-constrained portable or battery-powered rail, this is the part that avoids the inductor-height problem and keeps the BOM count low.
600 mA load ceiling and the fixed output
The single output is fixed at 1.225 V — no external resistor divider, no adjustment. That suits a 1.2 V core or I/O rail for a low-power MCU, FPGA auxiliary supply, or RF transceiver. The 600 mA continuous rating covers the typical load for those devices, but the fixed voltage means you cannot repurpose this part for a 1.8 V or 3.3 V rail without a different order code in the TPS6262x family.
6-DSBGA — layout and assembly reality
The 6-DSBGA package (0.4 mm ball pitch, 6 bumps) demands a controlled PCB stack-up. Fan-out traces between the bumps require a minimum 0.2 mm trace/space on the outer layer, and the centre bump is the ground return — via-in-pad with filled vias is the standard approach to avoid solder wicking. Reflow profile follows standard lead-free SAC305; MSL is typically 1 for DSBGA, but confirm the reel date code for moisture sensitivity.
