概述

Description

TPS54680PWPR is TI’s high‑efficiency synchronous buck regulator designed for point‑of‑load rails. It integrates a PWM controller with a pair of MOSFETs (high‑ and low‑side), enabling a compact DC‑DC converter for demanding rails such as CPU cores, memory, FPGAs, and ASICs. Key features typically include a wide input range, adjustable output via a feedback network, programmable switching frequency, fast transient response, soft‑start, enable/shutdown control, and comprehensive protections (overcurrent, overvoltage, overtemperature, UVLO) plus a power‑good signal. It can be used in multi‑phase configurations for higher current and efficiency. The PWPR suffix denotes the specific packaging variant (RoHS‑compliant) used by TI. For exact electrical specs, pinout, and thermal data, consult the TPS54680 datasheet and TI product page.

Features

Here are the key features of TPS54680PWPR (concise):
- Wide input range: suitable for automotive and multi-rail apps
- High output current: up to several amps (typical 6 A class)
- Adjustable output voltage via feedback
- High efficiency (typical >90%)
- Current-mode PWM control with programmable switching frequency
- Internal soft-start and output voltage tracking
- Enable/shutdown control
- Protections: cycle-by-cycle current limit, overcurrent/short-circuit protection, overvoltage protection, thermal shutdown
- Undervoltage lockout (UVLO)
- Remote sense option and supply monitoring
- Status/power-OK signaling
- Small PWPR package (with exposed pad) suitable for compact boards
Note: for exact electrical specs (input range, output range, current capability, and protection thresholds), please refer to the TI TPS54680 datasheet.

Package

TPS54680PWPR is available in an 8-pin WSON package (2.0 × 2.0 mm) with an exposed pad.

Pinout

TPS54680PWPR uses an 8-pin PWPR (WSON-8) package. Pin count: 8. Function: single-output buck regulator. Typical pins (high level): VIN (input power), GND (ground), LX (switch node to inductor), FB (output feedback), EN/UVLO (enable and undervoltage lockout), PGOOD (power-good), SS (soft-start), and one NC/Reserved pin.

Manufacturer

Manufacturer: Texas Instruments Incorporated (TI).
TI is a multinational American semiconductor company that designs and manufactures analog and embedded processing integrated circuits, microcontrollers, and other ICs used in a wide range of electronics.

Application

TPS54680PWPR is a high-efficiency buck regulator used for point-of-load power in compact systems. Typical applications include generating CPU/FPGA/ASIC core rails, memory voltages, and other low-voltage rails in servers, networking gear, telecom equipment, and data centers. It is also suitable for industrial automation and embedded electronics needing compact, reliable DC-DC conversion.
