B0505D-1WR3 产品概述

B0505D-1WR3 是 YLPTEC(易川) 推出的单通道隔离型 DC-DC 转换器,专为板上电源系统中需要产生与输入电源隔离的稳定 5V 输出而设计。该模块在尺寸小、效率高、保护完善的前提下,提供最高 1W 功率输出(输出电压 5V,最大电流 200mA),非常适合对体积和可靠性有严格要求的嵌入式系统与工业控制场合。

一、主要性能特点

  • 单路输出:1 路,Vout = 5.0V,Iout(max) = 200mA,输出功率 1W。
  • 工作输入电压:Vin = 4.5V ~ 5.5V,适合 5V 总线直接供电。
  • 高效率:转换效率可达约 88%,降低系统发热与功耗。
  • 隔离性能:隔离电压 1.5kV(Vrms),满足常见输入/输出隔离需求。
  • 保护功能:具备短路保护、自动故障恢复与过热保护,提升系统可靠性。
  • 工作环境:环境温度范围 -40℃ ~ +85℃,适用于宽温度应用。
  • 低输出纹波:典型纹波噪声 30mVp-p,最大容性负载 2400µF。
  • 开关频率:约 100kHz,有利于滤波器设计与 EMI 管控。

二、典型应用场景

  • 工业控制与数据采集模块的隔离电源;
  • 通信设备中为隔离信号链供电;
  • 安全测量与传感器接口(要求输入/输出电隔离);
  • 嵌入式系统、单板计算机或外设供电隔离。

三、电气与机械参数(摘要)

  • 输入电压:4.5 ~ 5.5V
  • 输出:5V / 200mA(1W)
  • 效率:≈88%
  • 隔离电压:1.5kV(Vrms)
  • 纹波:30mVp-p(典型)
  • 最大容性负载:2400µF
  • 开关频率:100kHz
  • 封装:DIP,外形尺寸 L×W×H = 12.7 × 8.2 × 10.16 mm

四、设计与布局建议

  • 输入侧建议接入低 ESR 电解或固态电容以降低纹波(参考 10µF~100µF,根据系统要求调整);
  • 输出侧允许大容性负载(最高 2400µF),但建议在靠近负载处布局滤波电容以抑制瞬态;
  • 保持输入/输出端与其他敏感信号的隔离距离,必要时加装共模 EMI 滤波器以抑制开关干扰;
  • 在高温或散热受限场合,预留一定散热空间并避免贴近高热器件。

五、注意事项与可靠性

  • 输入电压应保持在 4.5~5.5V 范围内,超过范围可能触发保护或影响寿命;
  • 短路保护为自动恢复型,但频繁短路会影响长期可靠性,应在系统层面避免持续短路状态;
  • 如需通过安全认证或在更高隔离等级下使用,请在设计阶段与供应商确认样品测试数据与认证资料。

B0505D-1WR3 以其小巧封装、高效率与完善的保护功能,适合对隔离电源有严格尺寸和可靠性要求的嵌入式与工业应用,能在保障系统稳定性的同时简化电源设计。若需详细电气特性曲线、典型应用电路或样品评估建议,可进一步提供具体需求以便匹配最佳方案。

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
