概述

Description

TPS627431YFPR is a Texas Instruments switching buck regulator (DC-DC converter) designed for battery-powered and portable electronics. It converts a higher input rail (e.g., from a battery or main supply) to a stable, lower output voltage with high efficiency. The device includes typical protection features such as enable control, overcurrent protection, and thermal shutdown, plus soft-start for reliable startup. The YFPR suffix indicates TI’s small, RoHS-compliant package (an 8-pin/pol package variant). Common applications include powering microcontrollers, sensors, and other ICs in wearables, IoT devices, and compact consumer electronics. For exact electrical parameters, pinout, and application circuits, consult the TI TPS627431 datasheet and product page.

Features

TPS627431YFPR Features (concise)
- High-efficiency step-down DC-DC converter designed for portable/battery-powered devices
- Wide input voltage range suitable for battery and USB applications
- Fixed or adjustable output versions available
- Enable pin to disable device with low leakage
- Internal soft-start to prevent inrush
- Cycle-by-cycle current limit protection
- Over‑temperature shutoff for safe operation
- Very low quiescent current for extended battery life
- Small package with minimal external components (suitable for compact designs)
Note: For exact electrical specs (input range, output voltage options, efficiency, etc.), please refer to the TI datasheet.

Package

TPS627431YFPR comes in an 8-pin VQFN package (2.9 x 2.9 mm) with an exposed pad.

Pinout

Pin count: 8 pins (VSSOP-8 in YFPR package).
Function: A switching DC-DC buck regulator (step-down converter) that converts a higher input voltage to a lower regulated output. It includes the internal switch and control circuitry; external inductor, input/output capacitors, and feedback/enable connections are required per the datasheet.

Manufacturer

Manufacturer: Texas Instruments (TI).
TI is an American multinational semiconductor company that designs, manufactures, and sells analog and embedded processing integrated circuits. It is a publicly traded, globally integrated leader in the semiconductor industry.

Application

TPS627431YFPR is a compact, high-efficiency step-down regulator. Applicable areas include:
