Overview

Description

TPS54614PWPR is a DC-DC buck regulator from TI’s SIMPLE SWITCHER family. It provides high-efficiency step-down conversion suitable for point‑of‑load rails in telecom, industrial, and consumer electronics. The device integrates a high‑side switch and control circuitry; it requires only a few external components (inductor, input/output capacitors, and a feedback divider) to generate a stable output. It supports a wide input voltage range and adjustable output; features include soft‑start, enable pin, voltage feedback loop, current limit, over‑temperature protection, and a Power-Good signal. The PWPR suffix denotes a specific TI packaging/pack option (surface mount, tape/reel, Pb‑free). Typical applications: CPU/GPU rails, FPGA logic, and microcontroller supplies. For exact specs (input range, output range, switching frequency, protections), refer to the TPS54614 data sheet and TI design guidelines.

Package

The TPS54614PWPR is supplied in a 20-pin HTSSOP (PowerPAD) package with an exposed thermal (bottom) pad. See the TI datasheet for exact mechanical dimensions.

Pinout

- Pin count: 20 pins (PWPR = 20-pin PowerPAD/VQFN-style package).
- Function: TPS54614 is a synchronous step‑down (buck) DC‑DC regulator with integrated MOSFETs (4 A continuous output capability), adjustable output via feedback, with typical control pins such as VIN, SW, BOOT, GND, FB, EN and PGOOD for point‑of‑load power conversion.

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
Type of company: TI is a multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits and power‑management devices (including DC‑DC converters like the TPS54614). It is publicly traded (NASDAQ: TXN) and headquartered in Dallas, Texas.

Application

TPS54614PWPR is a high‑efficiency 4-A step-down regulator. Suitable for:
- Point‑of‑load regulation for CPUs/GPUs, FPGAs, ASICs
- Telecom/networking power rails and data‑center subsystems
- Industrial/automation equipment (controllers, motor drives, PLCs)
- Automotive power‑management subsystems (wide input range)
- Consumer electronics and embedded systems needing compact, multi‑rail DC‑DC conversion
- Any distributed‑power design requiring a compact, wide‑input buck regulator

Equivalent

There are no guaranteed 100% drop‑in equivalents. Look for synchronous buck regulators that match VIN, VOUT range, ≥4–5 A output, switching frequency and the same package/pinout. Close alternatives to evaluate: TI TPS54618/TPS54620 family, Analog Devices/Linear Tech LTC3895 or LTC3851 (controller + external MOSFETs), and Monolithic Power Systems MPM36xx module/regulators. Always verify pin compatibility, compensation, thermal and layout differences before substituting.
