Product details

Fixed 3.3V rail with 1.2A continuous — what it covers

The TPS62082DSGR is a synchronous buck regulator delivering a fixed 3.3V output at up to 1.2A continuous, from an input range spanning 2.3V to 6V. That input window covers single-cell Li-ion (3.0V–4.2V) and 5V USB rails without a pre-regulator. The 2 MHz switching frequency lets the output filter use small-value inductors and ceramic capacitors, shrinking the total solution footprint on a 2-layer board.

Switching frequency and synchronous rectification

At 2 MHz the switching edges are fast enough that layout parasitics matter — keep the input cap within 2 mm of the VIN pin and the inductor close to the switch node.

Texas Instruments lists TPS62082DSGR as Active. ROHS3 compliant.

Frequently asked questions

What is a suitable replacement for TPS62082DSGR?

The LM53625LQURNLRQ1 is an automotive-grade (AEC-Q100) synchronous buck with a similar 2.1 MHz switching frequency and 2.5A output, but its minimum input is 3.9V — it won't run from a single Li-ion cell. The LMR33630APCQRNXRQ1 delivers 3A adjustable output with a wider input range (3.8V to 36V) but needs an external feedback divider. Neither is a drop-in; verify the BOM rail voltage, current, and temperature grade.
