TPS610981DSER

• Synchronous Step-Up (boost) DC/DC Converter
• 0.7 V to 4.5 V Input range, per the TI Part Title
• Single 3.4 V Output at 50 mA
• Ultra-Small 6-Pin WSON, 1.5 Mm X 1.5 Mm X 800 Um
• -40 C to +85 C Operating range; Lead Free and RoHS Compliant

The TPS610981DSER is a Texas Instruments synchronous boost (step-up) DC/DC converter supplied in a 6-pin WSON package measuring just 1.5 mm x 1.5 mm x 800 um. Per its TI part title it accepts an input from 0.7 V to 4.5 V and produces a single 3.4 V output at 50 mA, making it a very low input voltage converter intended for single-cell operation. Its boost topology allows the TPS610981DSER to hold the output rail as the source voltage falls well below the required level. The device is lead free and RoHS compliant, and is rated for a -40 C to +85 C operating range.

Boost converters that start and run from as little as 0.7 V are built for single-cell sources, since an alkaline, NiMH or coin cell spends much of its life below the 3.3 V a system needs. The TPS610981DSER supplies a fixed 3.4 V rail at up to 50 mA, which suits low-power sensor nodes, wireless tags and beacons, medical and health monitors, remote controls, and metering devices that spend most of their time asleep. Its 1.5 mm square WSON package lets it fit alongside the cell in space-limited enclosures. Typical buyers are battery-powered IoT and wearable product designers who need maximum usable capacity from a single cell.
