Product details

15 A point-of-load regulator with programmable output

The TPS62873Z1WRXSR is a single-output synchronous step-down (buck) converter delivering 15 A continuous from a 2.7 V to 6 V input rail. The output is programmable via external resistors from 0.4 V up to 3.35 V, covering the core and I/O supply voltages for modern FPGAs, ASICs, and processors. Four selectable switching frequencies — 1.5 MHz, 2.25 MHz, 2.5 MHz, and 3 MHz — let the designer trade off output ripple against efficiency and external component size. The synchronous rectifier eliminates the external Schottky catch diode, saving board area and reducing the BOM count. The 16-pin VQFN package with wettable flanks (2.55 mm × 3.55 mm) supports automated optical inspection (AOI) of the solder joints on the bottom-side thermal pad, a requirement for high-reliability assembly lines.

Temperature grade and junction range for industrial environments

The wide range also covers cold-start conditions down to -40°C. The 2.7 V minimum input allows operation from a 3.0 V rail during brownout or battery discharge.

Active lifecycle and compliance documentation

ROHS3 compliant, the part contains no restricted substances per EU Directive 2015/863. The supplier provides a full material declaration and REACH compliance data upon request through the standard documentation portal.

Frequently asked questions

What is the closest functional second-source to TPS62873Z1WRXSR — TPS65261RHBT?

The TPS65261RHBT is a different part: it is a triple-output (3-channel) buck converter with a maximum output current of 3 A per channel, compared to the single 15 A output of the TPS62873Z1WRXSR. The TPS65261RHBT also has a lower operating temperature ceiling of 85°C ambient versus 125°C junction. These are not drop-in replacements; a board redesign would be required.

What is the function of TPS62873Z1WRXSR?

It is a step-down (buck) switching regulator with synchronous rectification, delivering a programmable output voltage from 0.4 V to 3.35 V at up to 15 A from a 2.7 V to 6 V input rail.

What compliance documentation does Texas Instruments provide for TPS62873Z1WRXSR?

Texas Instruments provides ROHS3 compliance certification for this part. Full material declarations, REACH compliance data, and conflict minerals reporting are available through the TI documentation portal upon request.
