XC6702D331ER-G 产品概述

一、产品简介

XC6702D331ER-G 是 TOREX(特瑞仕)推出的一款高压、低功耗线性稳压器(LDO),固定输出 3.3V,最大输出电流 300mA。器件支持最高输入电压 36V,适用于工业与汽车类高压输入场景。封装为小型 DFN-6(USPC-6,1.8×2mm),集成多种保护与控制功能,是对空间、噪声与可靠性有较高要求系统的理想选择。

二、主要特性

  • 输出电压:固定 3.3V,输出极性为正极
  • 最大输出电流:300mA
  • 工作电压上限:36V
  • 压差(Dropout):1.2V @ 100mA(在更高负载下压差会增加,设计时应留有裕量)
  • 静态电流(Iq):典型 40µA,适合低功耗应用
  • 电源纹波抑制比(PSRR):65dB @ 1kHz,有效抑制输入纹波和噪声
  • 功能:使能控制、内置软启动、过流保护、短路保护、热关断
  • 工作温度:-40°C ~ +105°C(Ta)
  • 输出类型:固定输出,单通道

三、性能优势

  • 低静态电流与良好 PSRR:40µA 的待机电流配合 65dB@1kHz 的 PSRR,使器件在电池供电及噪声敏感的模拟/射频前端均表现优秀。
  • 高压输入兼容性:36V 的输入上限适合直接连接较高电压母线,减少外部预降压器件。
  • 完善的保护电路:内置软启动减少启动浪涌,过流/短路保护及热关断提高系统安全性和可靠性。
  • 小尺寸封装:1.8×2mm DFN-6 有利于高密度板级设计,同时需注意散热处理。

四、典型应用

  • 工业控制与测控设备(高电压母线到 3.3V 数字/模拟电源)
  • 汽车电子(需确认车规要求与具体环境下的额定限制)
  • 便携/电池供电设备(低静态电流有利于延长待机寿命)
  • 模拟电路、MCU、外设供电与噪声敏感的前端电源

五、设计与布局建议

  • 输入/输出去耦:建议在输入与输出端使用低等效串联电阻(ESR)陶瓷电容,典型值范围为 1µF–10µF(具体请参考器件手册中对电容类型与等效串联电阻的要求)。
  • 散热处理:DFN-6 小封装散热能力有限,建议在 PCB 下方敷铜热沉并使用多层过孔连接以提高导热能力,确保在高 Vin–Vout 差值与大电流情况下器件不会因功耗过高而触发热保护。
  • 输入电压裕量:注意压差随电流增加而上升,若在 300mA 工作点使用,应保证 Vin 至少比 3.3V 高出足够的余量,并评估功耗((Vin–3.3V)*Iout)。
  • 使能端:器件带有使能控制,推荐通过 MCU 或外部逻辑控制电源开关;具体使能电平与时序请参阅完整数据手册以避免误操作。
  • 保护与 EMI:在噪声或高干扰环境下,可辅以滤波网络和保护元件(如瞬态抑制器)保护输入端。

六、封装与可靠性

  • 封装:USPC-6(DFN-6)1.8×2mm,带中央露铜垫,用于散热与地连接。
  • 工作温度范围:-40°C~+105°C(Ta),适应较宽环境温度,但在高温高功耗工况下须关注热降额。
  • 建议在产品开发阶段通过实际 PCB 原型测试稳压器在目标负载与温度下的热、稳定性与保护动作情况。

总结:XC6702D331ER-G 将高压输入兼容、低静态电流与良好噪声抑制集于小尺寸封装,适用于工业、汽车与便携式电源方案。为保证长期可靠性,应重视输入裕量、散热布局与输出去耦电容的选择,必要时参考 TOREX 官方数据手册及布局指南进行最终设计验证。

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
