Product details

2.25 MHz buck for tight boards

The Texas Instruments TPS62272DRVR is a synchronous step-down (buck) converter delivering up to 400 mA from a 2 V to 6 V input rail.

400 mA load ceiling and what it means

The 400 mA continuous output current is the hard ceiling for this regulator. If your BOM rail needs 500 mA peak with a 300 mA average, the part handles it — but a steady 450 mA load pushes the junction temperature above the safe operating area at 85°C ambient. The synchronous rectifier (integrated low-side FET) keeps efficiency above 85% across most of the load range, so the thermal rise is manageable for typical 3.3 V or 2.1 V logic rails.

Active production, no LTB worry

For a production BOM line, this means you can qualify the part for new designs without planning a second-source migration in the next product cycle.

Frequently asked questions

What is the difference between TPS62272DRVR and TPS62270DRVR?

The TPS62270DRVR is the same base product family but with a fixed 1.8 V output and a 1.8 V to 6 V input range. The TPS62272DRVR offers a programmable output (with fixed 2.1 V and 3.3 V options) and a wider 2 V to 6 V input minimum. Both share the same 6-WSON package and 400 mA output rating. If your rail is 1.8 V, the TPS62270 is the direct fit; for 2.1 V or 3.3 V, the TPS62272 avoids an external divider.
