Product details

2A fixed 1.8V buck in SOT-583

The TPS6285020MQDRLRQ1 is a Texas Instruments automotive-grade synchronous buck regulator delivering a fixed 1.8V output at 2A continuous from a 2.7V to 6V input rail. The 1.8MHz to 4MHz switching frequency lets the designer trade off inductor size against output ripple — useful when the load is a sensor module or a CAN transceiver that needs a clean 1.8V rail without a separate LDO.

Active production — no EOL signal

The base product number TPS6285020 is the production root; the full order code TPS6285020MQDRLRQ1 is the automotive-qualified variant in SOT-583 on tape-and-reel.

Frequently asked questions

Is TPS6285020MQDRLRQ1 automotive qualified?

Yes — it carries the Automotive, AEC-Q100 series designation, which means it has passed the stress tests for automotive-grade ICs including high-temperature operating life and temperature cycling.

Does TPS6285020MQDRLRQ1 support fixed 1.8V output at 2A continuously?

Yes. The output is fixed at 1.8V (no external resistor divider needed) and the current rating is 2A continuous. The synchronous rectifier keeps efficiency high across the load range.

Can TPS6285020MQDRLRQ1 replace the base TPS6285020?

The base product number TPS6285020 is the same die; the full order code adds the automotive qualification and the specific package variant. If your BOM calls for the automotive-grade part, this is the correct order code.
