TPS54614PWPR

TPS54614PWPR is a Texas Instruments DC-DC buck (step-down) regulator used to generate a stable, lower voltage rail from a higher-voltage source for point-of-load power.
Key points
- Type: high-efficiency buck regulator suitable for fixed or adjustable output variants.
- Control: voltage-feedback with enable pin; features soft-start and protection (UVLO, current limit, overtemperature/thermal shutdown).
- Packaging: PWPR suffix indicates a RoHS-compliant small package (WSON/compact package) with tape-and-reel packaging.
- External components: requires an inductor and input/output capacitors; a catch diode if the design is non-synchronous (depends on variant).
- Applications: telecom, industrial, computer, and automotive power rails needing reliable on-board regulation.
Note: exact electrical specs, pinout, and features vary by variant. For precise details, consult the TPS54614PWPR datasheet from TI.

Here are the key features of the TPS54614PWPR:
- Wide input range (up to about 42 V) for automotive/industrial use
- Buck regulator with integrated high-side switch
- Output options: adjustable via feedback network or fixed versions
- Fixed-frequency, current-mode PWM control for fast load regulation
- High efficiency and low quiescent current (especially at light load)
- Enable (ON/OFF) pin for sequencing and shutdown
- Protection suite: undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown, and overvoltage protection
- Soft-start and controlled inrush to prevent supply surge
- External inductor and diode (or synchronous rectification in some configurations)
- Low external component count and compact design
- Thermally enhanced PowerPAD package (PWPR) for excellent heat dissipation
Note: Exact fixed/adjustable output options and requirements (diode vs. synchronous) depend on the specific circuit configuration.

- Pin count: 16 pins
- Function: High-efficiency buck (step-down) DC-DC converter with integrated high-side MOSFET; provides adjustable output via feedback network and includes enable, soft-start, and protection features (OC/thermal).

Texas Instruments (TI) is the manufacturer. TI is an American multinational semiconductor company that designs and manufactures analog, power management, and embedded processing integrated circuits for electronics.
