WRA0512S-3WR2 产品概述

WRA0512S-3WR2 是 YLPTEC(易川)推出的一款超小型 SIP 封装隔离双输出直流-直流模块,面向对空间、隔离和低噪声有较高要求的嵌入式及工业应用。该器件在 4.5V~9V 宽输入范围内工作,提供 ±12V 对称输出,单体体积小(22×9.5×12 mm),并集成多种保护功能,适合电力、工控、通信、物联网及汽车等领域的辅助电源或信号隔离电源解决方案。

一、主要技术参数

  • 输入电压(Vin):4.5V ~ 9V(2:1 宽输入范围)
  • 输出通道数:2(±输出)
  • 输出电压(Vout):±12V
  • 输出功率:3W(总功率)
  • 输出电流(最大值):104 mA(每路最大)
  • 转换效率:典型 74%
  • 隔离电压(Vrms):1500 VDC
  • 开关频率:300 kHz
  • 纹波噪声:100 mVp-p(典型)
  • 最大容性负载:470 μF(每路)
  • 保护功能:短路保护(自恢复)、欠压保护、过流保护、输出可关断(Shutdown)
  • 工作温度:-40 ℃ ~ +85 ℃
  • 封装:SIP,尺寸 22 mm × 9.5 mm × 12 mm

二、关键特性解析

  • 超小体积:SIP 小封装便于在 1U/板级、狭小空间内布置多路电源,适合体积受限的嵌入式设备。
  • 双向对称输出:±12V 输出对称、稳定,适合为模拟放大器、数据采集前端和隔离信号链路提供正负电源。
  • 高隔离:1500 VDC 隔离等级可实现信号/功率隔离,满足多数工业接口与地回路隔离需求。
  • 低纹波噪声:典型 100 mVp-p,适用于对噪声敏感的模拟电路或 ADC 前端(仍建议在关键场合加额外滤波)。
  • 保护完善:短路自恢复、欠压与过流保护降低系统风险,模块支持外部使能/关断,便于系统电源管理。
  • 宽温度与高可靠性:-40 ℃~+85 ℃ 的工作范围满足苛刻工控和汽车电子环境要求(实际使用建议按温升进行降额设计)。

三、应用场景

  • 工业控制(PLC、传感器隔离电源、低功耗驱动模块)
  • 通信设备(基站子模块、隔离供电)
  • 电力系统(测量与保护电路的隔离辅助电源)
  • 物联网网关与边缘设备(空间受限的低功耗供电)
  • 汽车电子(车载传感或数据采集模块的隔离电源,需结合车规认证评估)

四、设计建议与使用注意

  • 输入端去耦:为保证稳定性与抑制开关噪声,模块输入侧建议靠近模块引脚放置低 ESR 的旁路电容(例如 10 μF ~ 100 μF),并加 0.1 μF 陶瓷并联高频滤波。
  • 输出滤波与最大容性负载:模块允许的最大容性负载为 470 μF;若在输出端使用大容量电解或钽电容,应确保 ESR 与等效回路不会导致启动或稳定性问题。对高精度模拟电路建议在输出加额外低通滤波器或 L-C 网以进一步降低纹波。
  • 散热与降额:尽管效率较高(典型 74%),在满载或高温环境下仍会有发热,建议在 PCB 设计中为模块提供适当的散热路径(接地铜箔扩展)并在高温工况下进行功率降额。
  • 布局建议:输入、输出走线尽量短且粗,减少回流环面积以降低 EMI;敏感模拟地线应与开关地分离并在合适点汇流。
  • 隔离与安规:1500 VDC 隔离适用于一般工业隔离需求;若需进行更高等级的安规认证,请在整体系统设计时考虑爬电距离、爬痕等级和外壳接地等因素,并根据标准进行耐压测试。
  • 保护与复位行为:短路保护为自恢复类型,发生短路后模块会进入保护并在故障解除后自动恢复,系统设计中应考虑复位时序与上电顺序避免误动作。输出可关断功能便于实现系统级电源管理,请参阅具体使能逻辑电平要求(使用前确认模块引脚定义与控制电平)。

五、总结

WRA0512S-3WR2 以其超小体积、±12V 对称输出、1500 V 隔离及完善的保护功能,为空间受限且需隔离低噪声供电的应用提供了一种高性价比的解决方案。设计时应重视输入/输出去耦、散热与容性负载限制,并在高可靠性场合根据实际工况进行电气与热性能验证,以确保长期稳定运行。若需引脚定义、典型接线图或详细电气特性曲线,建议参阅厂商完整数据手册或联系技术支持。

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.
