Product details

1.6 MHz buck regulator in a SOT-23-5 — what that means for the rail

The Texas Instruments LM2830XMFX/NOPB is a 1.6 MHz step-down (buck) switching regulator delivering up to 1 A from a 3 V to 5.5 V input rail. The output is adjustable from 0.6 V up to 4.5 V.

Active lifecycle — no obsolescence risk for new designs

The LM2830XMFX/NOPB carries an Active product status with ROHS3 compliance. There is no last-time-buy notice, no NRND flag, and no official successor announced. For a BOM line, this means the part is qualified for new production runs and there is no urgency to qualify a drop-in replacement.

Frequently asked questions

Is LM2830XMFX/NOPB obsolete?

No. The LM2830XMFX/NOPB has an Active product status with no last-time-buy or end-of-life notice. It is suitable for new designs and ongoing production.

What is the switching frequency of LM2830XMFX/NOPB?

The switching frequency is 1.6 MHz. This allows the use of a smaller inductor compared to lower-frequency regulators, saving board space.

Does LM2830XMFX/NOPB require external compensation?

Yes. The LM2830XMFX/NOPB is a non-synchronous buck regulator that requires an external Schottky catch diode and compensation components. The datasheet provides typical application circuits with component values.
