Product details

750 kHz switching with synchronous rectifier

Switching at 750 kHz lets you pick a smaller inductor — typically 4.7 µH to 10 µH — than a 300 kHz part, at the cost of slightly higher switching losses.

Industrial temperature grade, not extended

That covers most indoor and outdoor telecom, industrial control, and battery-powered equipment, but not under-hood automotive or high-density server racks where ambient exceeds 85°C.

Frequently asked questions

Is TPS62003DGS obsolete?

No. The product status is Active with no end-of-life notification from Texas Instruments.

Does TPS62003DGS have a Power Good (PG) pin?

The evidence does not list a PG pin. The TPS62003DGS is a basic fixed-output buck without a power-good flag — if your design requires sequencing or voltage monitoring, consider the TPS62081DSGR which includes a PG output.

When sourcing TPS62003DGS, what is the closest functional second-source?

The TPS62081DSGR is in a different package (DSG-8, 2.0 mm × 2.0 mm), so the PCB footprint is not identical. For a pin-to-pin replacement, stick with the TPS62003DGS.
