Frequently Asked Questions

What input voltage range does TPS628680ARQYR support and how does it handle single-cell Li-Ion batteries?

TPS628680ARQYR accepts an input voltage from 2.4 V to 5.5 V, which covers a single-cell Li-Ion battery across its full discharge range of approximately 2.7 V to 4.2 V. This allows the converter to supply regulated output without needing a boost stage, simplifying the power tree and reducing BOM cost in portable devices.

How does the I2C interface on TPS628680ARQYR enable dynamic voltage scaling in processor-based systems?

The I2C interface allows firmware to adjust the output voltage in real time, supporting dynamic voltage and frequency scaling (DVFS) across processor operating modes. Output voltage steps are programmable in increments of approximately 10 mV, enabling smooth transitions between performance and low-power states without the 140 µs glitches common in analog feedback adjustments.

For a compact motor-control or IoT PCB layout, how much board space does the TPS628680ARQYR QFN-9 package require?

The QFN-9 package measures only 1.5 mm x 2.5 mm, occupying 3.75 mm² of board area. Combined with small 1 µH or 2.2 µH inductor options, the complete power stage fits within 15 mm² — roughly 4x smaller than comparable TO-252 or SOIC-8 solutions delivering the same 4 A output current.
