Product details

300 mA buck in a 0.4 mm pitch DSBGA — the power-density play

The Texas Instruments TPS62748YFPT is a synchronous step-down (buck) converter rated for 300 mA continuous output. The programmable output voltage is set to either 1.2 V or 1.8 V, targeting low-voltage core rails for MCUs, Bluetooth LE SoCs, and sensor nodes.

1.2 MHz switching — inductor size and ripple trade-off

The 1.2 MHz switching frequency lets the designer use a small inductor (2.2 µH to 4.7 µH range) and keeps the fundamental ripple above the audio band. The trade-off is higher switching losses at very light loads — below 10 mA the efficiency curve drops faster than a 600 kHz part would.

125°C junction — industrial and automotive edge

The 8-DSBGA package (0.4 mm ball pitch) requires a controlled solder profile and a clean PCB surface finish — ENIG or OSP, not bare copper.

The base product number TPS62748 covers multiple output-voltage and package variants, so a future BOM respin to a sibling code is possible without a full qualification cycle.

Frequently asked questions

Is TPS62748YFPT the same as TPS62748YFPR?

The TPS62748YFPT and TPS62748YFPR share the same base product number TPS62748 and the same 8-DSBGA package. The suffix difference (PT vs PR) typically indicates a different tape-and-reel packing quantity or reel diameter. Functionally they are identical — the same die, same electrical specs. Confirm the reel quantity with your distributor before ordering.

Can TPS62748YFPT be used in a 2-cell battery application?

Yes. The input voltage range of 2.15 V to 5.5 V covers a 2-cell alkaline stack (2.4 V fresh down to 2.0 V depleted) and a 2-cell NiMH stack (2.4 V nominal). The minimum input of 2.15 V leaves headroom for the 1.8 V output option. For a 2-cell Li-ion stack (7.4 V nominal), the 5.5 V maximum input is exceeded — that application needs a different converter.

Does TPS62748YFPT come in a tape and reel package?

The 8-DSBGA package is a wafer-level chip-scale package, so the tape pocket is designed for the bare die footprint with no molded body. The reel quantity varies by the TR suffix — confirm the exact count with the distributor.

Is TPS62748YFPT RoHS compliant?

No explicit RoHS certification code appears in this listing, but the DSBGA package is lead-free by design. Verify the date-code-specific RoHS status on the manufacturer's website or request a certificate of compliance with your order.
