WD3168E-6/TR —— WILLSEMI(韦尔)300mA 升压型 DC-DC 电源芯片 概述

一、产品简介

WD3168E-6/TR 是韦尔(WILLSEMI)推出的一款高频升压型 DC-DC 转换器,适用于将低电压电源提升至约 5V 输出,为便携设备和嵌入式系统等提供稳定电源。器件采用 SOT-23-6L 小封装,支持宽输入电压范围与中等负载能力,适合空间受限要求高频率降噪与小尺寸外设设计。

二、主要性能参数

  • 工作电压 Vin:2.7V ~ 5.5V
  • 输出电压 Vout:4.8V ~ 5.2V(目标输出)
  • 输出电流 Iout:300mA(典型)
  • 静态电流 Iq:2mA
  • 等效输出电阻:6Ω
  • 能量效率:约 80%(典型工况)
  • 开关频率:1.7MHz
  • 工作温度范围:-40℃ ~ +85℃
  • 封装:SOT-23-6L
  • 功能类型:升压(Boost)
  • 型号与包装:WD3168E-6/TR(TR 常指卷带包装)

三、关键特性与优势

  • 高频工作(1.7MHz)便于使用小型电感与陶瓷电容,整体方案体积小巧,适合紧凑型产品。
  • 低静态电流(2mA)有利于待机功耗控制,适合移动与电池供电场景。
  • 典型效率约 80%,在常见负载下能提供较好能量转换性能,兼顾发热与电源稳定性。
  • 宽输入电压范围支持单节锂电池与多种供电架构,输出稳定至 5V ±0.2V,满足多数 5V 外设需求。

四、典型应用场景

  • 单节锂电池或小容量电源升压至 5V,为传感器、MCU、通信模块或外设供电;
  • 便携式仪器、可穿戴设备和便携充电设备的备用 5V 输出;
  • 小功率 USB 辅助供电、外设供电模块;
  • 其它空间受限且需要 5V 稳压输出的嵌入式应用。

五、设计与使用建议

  • 高频率下应选用低损耗、饱和电流足够的功率电感,配合低 ESR 的输入/输出电容以保证稳定性与低纹波;
  • PCB 布局需尽量缩短信号回路,电感、电容与芯片引脚靠近布置,地线采用单点或短路径接地以降低噪声;
  • 在接近最大输出电流工作时注意散热,合理估算功耗与器件温升,必要时增大铜箔散热区域;
  • 根据负载特性选择合适的开关器件与滤波元件,评估等效输出电阻(6Ω)对启动、峰值电流及短路行为的影响。

六、包装与采购提示

WD3168E-6/TR 提供 SOT-23-6L 封装并以卷带(TR)方式供货,适合自动贴片生产线。采购时请确认规格书版本与管脚定义,索取样品并做评估测试以确保在目标系统中达到预期性能。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
