Product details

Input range and what it powers

The TPS61252DSGT: This is a boost converter with a 2.3 V to 6 V input range — it pulls a single-cell Li-Ion battery down to near its depletion voltage, or runs from two alkaline cells. The output side steps that up to a regulated rail for the downstream load. The listed applications — PDAs, portable audio/video, smartphones — tell you this part was designed for handheld gear where the battery voltage sags under load and the converter has to keep the rail steady.

The 8-WFDFN exposed pad (8-WSON 2x2 mm) is a small footprint with a thermal pad underneath.

Frequently asked questions

Is TPS61252DSGT a boost or buck converter?

It is a boost converter. The 2.3 V to 6 V input range steps up to a higher output voltage — typical for battery-powered portable devices that need a regulated rail above the battery voltage.

Does TPS61252DSGT require an external inductor?

Yes, like most non-module boost converters, it requires an external inductor and input/output capacitors. The specific inductor value and saturation current rating depend on the input voltage, output voltage, and load current; the datasheet provides recommended values for typical application circuits.
