Product details

Synchronous boost converter in a 1.67 mm² DSBGA

The Texas Instruments TPS61282AYFFT is a synchronous step-up (boost) DC/DC converter delivering up to 4A through the integrated switch at a 2.3MHz switching frequency. The output is programmable between 2.85V and 4.4V from an input range of 2.3V to 4.85V — a natural fit for single-cell Li-ion or 3.3V-rail boost applications where board area is the binding constraint.

Voltage envelope and output programmability

The input range bottoms at 2.3V and tops at 4.85V, so it will boost a near-depleted Li-ion cell (2.5V–2.7V cutoff) but cannot survive a 5V USB rail without front-end protection. The output is programmable, not fixed — the datasheet's resistor-divider setting determines the regulation point between 2.85V and 4.4V. The 4.4V ceiling means this part cannot produce a 5V output, which may be a deal-breaker for USB OTG or 5V sensor rails.

Package — DSBGA assembly realities

The 16-DSBGA package measures 1.67 x 1.67 mm. It requires a solder-paste stencil, a reflow oven, and X-ray inspection to verify ball wetting.

Any available stock carries date codes from the last production run, and buyers should verify date-code authenticity and traceability.

Frequently asked questions

Does TPS61282AYFFT support output voltages up to 5V?

No. The maximum programmable output voltage is 4.4V. The part cannot produce a 5V rail. If 5V output is required, a different boost converter with a higher output ceiling is needed.

What is the difference between TPS61282A and TPS61282AYFFT?

The TPS61282AYFFT is the specific DSBGA package variant (16-DSBGA, 1.67x1.67 mm). The base product number TPS61282A covers the same boost converter core, but the YFFT suffix identifies the wafer-level chip-scale package. Other package variants may exist under the same base number.
