What this 6-bump DSBGA buck does for your board
The TPS62674YFDT is a fixed-output step-down buck from Texas Instruments, delivering 500 mA at 1.26 V from a 2.3 V to 4.8 V input rail.
Fixed 1.26 V rail — no feedback divider needed
Output is fixed at 1.26 V, so the FB pin ties directly to the output — no external resistor divider. That saves two components and removes a tolerance stack. The 500 mA continuous rating suits low-voltage core rails, I/O supplies, or always-on standby regulators in portable gear. Compare that to the automotive LM53625LQURNLRQ1, which switches at 2.1 MHz and delivers 2.5 A, but needs a larger inductor and targets a different thermal envelope.
Active production — sourcing is straightforward
The 6-bump DSBGA package is a wafer-level chip-scale package. Reel or cut-tape options available. Stock and pricing confirmed per RFQ — no shelf claim, but active status means multi-source distribution access.
6-DSBGA — the bumps are on a fine pitch. Stencil aperture and solder volume need tight control. Input voltage range 2.3 V to 4.8 V maps to single-cell Li-ion, 3.3 V or 5 V rails — the 4.8 V max means it's not for 12 V buses.
