TPS54310QPWPRQ1

TPS54310QPWPRQ1 is TI’s 3-A, wide-input buck regulator with an integrated high-side switch (a member of the SimpleSwitch buck family). It’s designed for compact, efficient DC-DC conversion in automotive and industrial applications.
Key points:
- Wide input range: typically 4.5–42 V, suitable for automotive and telecom rails.
- Output: adjustable via external feedback resistors (fixed-output variants may exist); can deliver up to about 3 A.
- Integrated: power MOSFETs and control circuitry in a compact package (QPWPRQ1 denotes the specific RoHS-qualified package).
- Switching: fixed-frequency PWM, easy external compensation for stable output.
- Protections: undervoltage lockout, overcurrent/short-circuit protection, and thermal shutdown.
- Applications: point-of-load supplies, pre-regulation stages, automotive/industrial power rails.
For exact electrical specs, pinout, typical application circuits, and package details, refer to the TPS54310 datasheet and TI product page.

- Function: TI TPS54310QPWPRQ1 is a 3-A step-down (buck) DC-DC regulator with an integrated high-side switch and controller. It accepts Vin up to about 42 V and provides an adjustable output via an external feedback network, using the SW node to an external inductor (and diode or synchronous rectifier). Includes EN, soft-start, overcurrent protection, and thermal shutdown.

Manufacturer: Texas Instruments Incorporated (TI).
What kind of company: An American multinational technology and semiconductor company that designs and manufactures analog, embedded processing, and power-management integrated circuits for various industries.

TPS54310QPWPRQ1 is a 3-A step-down converter (28-V input, automotive-grade). Key application areas:
- Automotive power rails (12–24 V to 3.3/5 V) in ECUs, infotainment, sensors
- Industrial equipment and factory automation (24-V systems, point-of-load regulation)
- Telecom/networking gear (powered from 12–24 V rails)
- Consumer/embedded electronics (docks, adapters, compact power supplies)
- Any space-constrained design needing a high-efficiency buck regulator from a higher rail to logic voltages

TPS54310QPWPRQ1 uses the PWPR package, which is TI’s WSON-8 package (about 2.9 mm × 3.0 mm, RoHS-compliant).
