B0505S-2WR3 产品概述(YLPTEC 易川)

一、产品简介

B0505S-2WR3 是 YLPTEC(易川)推出的一款单通道隔离式 DC-DC 电源模块,输出功率 2W,输入工作电压范围 4.5V ~ 5.5V,输出稳压 5V,最大输出电流 400mA。模块采用紧凑 SIP 封装(19.5 × 7 mm),具有高达 1.5kV 的输入/输出间隔离能力,适用于对地隔离、信号隔离与电源去耦的小功率场合。

二、主要电气参数与性能

  • 通道数:1
  • 输入电压 Vin:4.5V ~ 5.5V(典型 5V 输入)
  • 输出电压 Vout:5V(稳压)
  • 输出电流(最大):400mA
  • 输出功率:2W
  • 转换效率:典型 84%(满载条件)
  • 最大容性负载:2400µF(大电容启动与稳定性需注意)
  • 隔离电压:1.5kVrms
  • 特性:短路保护、低功耗

按典型效率与满载计算的输入电流约为 Iin ≈ Pout/(Vin·η) ≈ 2W/(5V·0.84) ≈ 0.48A,设计时建议留有裕量。

三、功能与保护

模块具备短路保护与低功耗特性,能在异常负载或短路条件下保护自身及外接电路,降低系统风险。同时待机与空载损耗较低,适合对功耗敏感的电池供电或低功耗系统。具体的短路恢复行为与限流特性建议参考厂方详细数据手册以获得准确工作模式说明。

四、封装与热管理

SIP 小型封装(19.5×7 mm),便于垂直插装或板上直接焊接,节省 PCB 面积。由于模块功率密度较高,设计时应注意:

  • 在模块底部与周围预留散热通道,避免直接覆盖;
  • 若工作在高环境温度或长时间满载,应采取强制风冷或增加散热铜箔以利散热;
  • PCB 安装时避免将热敏器件紧邻模块热源。

五、应用场景与设计建议

适用于工业控制、仪表采集、通信设备、传感器隔离、地环路抑制与信号链隔离等场合。设计建议包括:

  • 输入/输出端各并联去耦电容:常规建议在输入端并联 10µF 电解 + 0.1µF 陶瓷,输出端同样配置 10µF/0.1µF 组合以抑制瞬态;注意总容性负载不超过 2400µF;
  • 布局上尽量将大电流回路短、粗,输入端与模块间走线阻抗低;
  • 若系统对 EMI/EMC 敏感,可在输入端加 LC 滤波器或共模电感,并按 EMC 标准进行验证;
  • 在多模块或多通道系统中,考虑隔离地的合理连通或单点接地,利用模块隔离特性实现信号与电源隔离。

六、选型与注意事项

选择 B0505S-2WR3 时,请确认:系统需要 5V 输入并输出隔离 5V、最大负载不超过 400mA、对隔离等级要求在 1.5kV 左右。若需更高输出功率、更大电流或更高隔离电压,请参考 YLPTEC 的其他系列产品。最终设计前建议获取并阅读厂家完整数据手册,确认短路保护恢复模式、工作温度范围及安全/寿命测试报告,以确保在具体应用中的可靠性与合规性。

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
