Product details

Input range and output current — what they mean for the BOM

The 3.3 V minimum and 5 V maximum input voltage define a narrow-VIN part for regulated 3.3 V or 5 V buses.

Switching frequency trade-off

Select 700 kHz for better efficiency at higher input voltages or lighter loads; select 1 MHz to shrink the inductor and output capacitor values. At 1 MHz the switching losses are higher, but the passives footprint shrinks — a meaningful choice when board area is tight. The D-CAP+™ architecture gives fast transient response without external compensation, which simplifies the BOM.

Temperature grade and environment

Rated for -40°C to 85°C ambient. That is industrial temperature, not automotive — no AEC-Q100 qualification here. Suitable for base-station line cards, networking equipment, industrial control boards, and test instrumentation.

Lifecycle and sourcing

No last-time-buy risk.

Frequently asked questions

Is TPS51461RGET a synchronous buck converter?

Yes, it integrates a synchronous rectifier, so no external Schottky diode is needed.

What package does TPS51461RGET come in?

It comes in a 24-VFQFN exposed pad package (supplier device package 24-VQFN, 4x4 mm). Available in Tape & Reel or Cut Tape.

Is TPS51461RGET obsolete or active?

Active. No end-of-life notification. ROHS3 compliant.

Is TPS51461RGET suitable for point-of-load regulation?

Yes. The 3.3 V to 5 V input range and 6 A output make it a good fit for POL regulation off a system 5 V rail, such as FPGA core or DDR memory supplies.
