WRA0515S-3WR2 产品概述

WRA0515S-3WR2 是 YLPTEC(易川) 推出的一款超小型 SIP 封装隔离型 DC-DC 转换器,单组输入、双极性输出设计,额定输出功率 3W。器件体积小(22 × 9.5 × 12 mm)、效率高、隔离强、保护完备,适合对体积与可靠性有严格要求的嵌入式电源与隔离供电场合。

一、主要电气性能

  • 输入电压范围:4.5V ~ 9V(宽输入比约 2:1)
  • 输出电压:±15V(对地双极性输出)
  • 额定输出功率:3W(双通道合计)
  • 单路最大输出电流:83mA
  • 峰值转换效率:约 74%
  • 开关频率:300kHz
  • 纹波噪声:典型 100 mVp-p
  • 最大容性负载:220 μF
  • 隔离电压:1500 Vrms(1500VDC 等效)

二、保护与可靠性特性

  • 短路保护(自恢复):在输出短路或过载时自动限流并在故障消除后自动恢复
  • 欠压保护与过流保护:提高系统可靠性并防止器件损坏
  • 工作温度范围:-40 ℃ ~ +85 ℃,适用于严苛环境
  • 隔离结构有助于降低地环路干扰并满足基本安全隔离需求

三、机械与封装

  • 尺寸:22 mm (长) × 9.5 mm (宽) × 12 mm (高)
  • 封装形式:SIP(适合插针式安装或焊接于 PCB)
  • 超小体积便于高密度电路板布局,特别适合空间受限的模块化设计

四、应用场景

  • 工业控制与自动化:用于隔离传感器、放大器或驱动电路的局部电源
  • 通信与网络设备:为隔离收发器、接口芯片提供对地双电源
  • 物联网与嵌入式终端:体积小、低功耗且具备隔离的供电方案
  • 汽车电子(根据具体认证与系统要求选型):可用于车载辅助模块的隔离供电

五、系统集成与使用建议

  • 输入输出去耦:建议在输入端并联低 ESR 电容以抑制输入瞬态,输出端根据负载特性选择合适的容性负载(不超过 220 μF)以避免稳定性问题。
  • 热设计与功率余量:在高温或全负载时效率约 74%,请留有热余量或采用散热/通风措施;超过额定温度应按厂商温度降额曲线使用。
  • EMI 与接地:尽管为隔离型模块,系统布局仍需注意输入、输出和信号地的合理走线与滤波,必要时加装共模滤波器与屏蔽。
  • 控制与关断:器件支持输出关断功能(具体管脚逻辑与使用方式请参阅数据手册),便于系统电源管理与节能。
  • 保护协调:在关键应用中建议结合外部保险丝、ESD 抑制器以及输入电压监测电路,提升系统整体可靠性。

六、选型与注意事项

  • 若需更高输出电流或更大功率,应选择额定更高的系列产品或并联方案(并联需确认共享和稳定性支持)。
  • 关注实际工作环境温度、负载占空比与纹波需求,根据效率和热耗进行设计验证。
  • 对于安全等级和汽车级应用,请咨询厂商获取完整认证信息与建议方案。

WRA0515S-3WR2 以小巧尺寸、完全隔离和多重保护为特点,适合在要求空间受限且需隔离隔阻抗、电气安全与稳定性的各类应用中作为高性价比的电源解决方案。详细电气参数、引脚定义与典型应用电路请参考产品数据手册。

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
