B0505LS-1W 产品概述

一、产品简介

B0505LS-1W 是 YLPTEC(易川)推出的一款单路隔离型 DC-DC 模块,校验通过!该器件采用 SIP 封装,输入 4.5V~5.5V,输出固定 5V,输出功率 1W,转换效率约 80%,适合尺寸受限且要求隔离的小功率点对点供电场合。

二、主要电气参数

  • 输入电压(Vin):4.5V ~ 5.5V
  • 输出电压(Vout):5V(固定)
  • 输出功率:1W,最大输出电流 200mA
  • 转换效率:约 80%
  • 隔离电压(Vrms):1.5kV
  • 最大容性负载:200µF
  • 纹波噪声:60mVp-p(典型)
  • 开关频率:100kHz
  • 特性:短路保护
  • 工作温度范围:-40℃ ~ +85℃

三、机械与封装

模块为 SIP(单列直插)封装,典型外形尺寸为 19.5mm × 10mm × 6mm,适用于垂直插装或插针式焊接到 PCB。小巧体积便于在空间受限的系统中布置,并可结合散热设计满足较宽的工作温度范围。

四、性能与保护特性

B0505LS-1W 提供 1.5kV 隔离,能有效阻断地环路和共模干扰,适合信号隔离、逻辑电平隔离及工业测控前端供电。模块内置短路保护,在异常负载或瞬态短路时可自动保护器件及外部系统,提升系统可靠性。80% 的典型转换效率在同类产品中处于合理水平,热量需通过合理的 PCB 走铜与环境散热管理处理。

五、典型应用场景

  • 工业控制与测量:用于传感器/采集模块与主控之间的隔离供电
  • 通信与接口电路:为隔离收发器、光耦驱动等提供独立电源
  • 仪器仪表:前端隔离电源、测试台供电
  • 医疗电子(非侵入类)、安防和交通控制等需低功耗隔离场合

六、使用建议与注意事项

  • 输入/输出侧建议并联适当低 ESR 电容(注意不超过最大容性负载 200µF),以降低瞬态和纹波。
  • 输出稳定负载时效率与温升相关,建议在高温或满载条件下进行额外散热(增大 PCB 铜皮、良好对流)。
  • 避免长期超载运行;短路保护为保护功能,不应作为长期异常工作策略。
  • 在高 EMI 环境中,可在输入端并联 LC 滤波器和 TVS 以提高抗干扰能力与瞬态抑制。
  • 布线时注意将敏感信号远离开关源和变压器耦合区域,减小耦合噪声对系统的影响。

七、小结

B0505LS-1W 是一款面向小功率隔离供电需求的成熟方案,具有良好的电气隔离、短路保护和紧凑尺寸,适合工业控制、信号采集与通信接口等需要隔离且空间受限的应用。用户在设计时注意热管理、滤波与容性负载限制,可获得稳定可靠的使用体验。

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
