B2405LS-1WR3 产品概述
一、产品简介
B2405LS-1WR3 是 YLPTEC(易川) 提供的一款小体积、高效率、隔离型微功率 DC/DC 模块。该模块针对板上电源系统中需要将输入总线电压隔离出一组辅助电压的场合设计，输入端以典型 24V 档（工作电压 21.6V ～ 26.4V）为主，输出为 5V 单路、最大输出功率 1W，适合在空间受限且需电气隔离的系统中使用。
二、主要电气参数
- 输入电压：21.6V ～ 26.4V（典型 24V 总线）
- 输出电压：5V（额定）
- 输出功率：1W，最大输出电流 200mA
- 转换效率：典型 88%
- 隔离耐压：1.5kV（Vrms）
- 开关频率：100kHz
- 最大容性负载：2400µF
- 纹波噪声：30mVp‑p（典型）
- 静态电流：1mA
- 工作温度：-40℃ ～ +85℃
- 保护功能：短路保护、自动故障恢复、过热保护
- 封装：SIP‑4，外形尺寸 19.5 × 6 × 10 mm
三、功能与保护特性
模块具备短路保护与过热保护，并支持自动故障恢复：当输出短路或过流触发保护时，模块进入保护状态并在故障解除后自动恢复正常输出，避免人工干预。模块为隔离型非稳压输出设计，要求输入电源较为稳定（推荐输入电压变化不超过 ±10%），以保证输出在容许范围内稳定工作。
四、典型应用场景
适用于需要隔离的板级供电场合，尤其是基于 24V 总线的工业与楼宇控制系统。典型应用包括：
- 纯数字电路、MCU 供电
- 继电器驱动及外围逻辑电路
- 数据交换/通信接口电源（需隔离）
- 一般低频模拟电路（对精密度要求不高的场合）
对于对输出精度、瞬态响应或低噪声有严格要求的高精度模拟前端，应评估是否需要额外的后级稳压或滤波处理。
五、安装与使用建议
- 输入侧建议并联适当的去耦电容以抑制瞬态；模块要求输入稳定，避免长时间超出额定范围。
- 输出侧注意最大容性负载 2400µF，过大的无源电容会影响稳定性或启动性能。建议使用低 ESR 的电容以降低纹波。
- 模块散热依赖自然对流，满载或高温环境下应保证良好通风或加装散热条件，必要时对输出电流进行热降额。
- 为满足隔离与安全要求，布局时保持足够的爬电距离和间隙，并考虑输入与输出端的屏蔽与接地策略。
- 由于开关频率为 100kHz，布线应尽量缩短高频回路，减小串扰与辐射。
六、封装与选型信息
型号：B2405LS-1WR3
品牌：YLPTEC(易川)
封装：SIP‑4，尺寸 19.5 × 6 × 10 mm，适合插装或焊接到 PCB。选型时确认所需隔离等级、输出纹波及容性负载能力，以匹配目标系统可靠性要求。
七、总结
B2405LS-1WR3 在体积、效率和隔离性能之间取得平衡，适合在 24V 工业总线或嵌入式板级系统中为数字、继电器及通信电路提供隔离 5V 电源。使用时注意输入稳定、电容负载限制和散热处理，必要时配合后级稳压或滤波以满足更高的输出精度与噪声要求。若需进一步的电气曲线或样品资料，可联系供应商获取详细数据手册。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
