B0505S-W2R2 产品概述
一、产品简介
B0505S-W2R2 是 YLPTEC（易川）推出的一款小体积、高效率的隔离型微功率 DC/DC 模块。模块采用定电压输入、隔离非稳压单路输出设计，额定输出功率 0.25W，专为在板上电源系统中需要产生与输入电源隔离电压的场合而设计。器件体积仅为 SIP 11.5 × 6 × 10 mm，适合空间受限的嵌入式与工业控制应用。
二、主要参数
- 输入电压（Vin）：4.5 V ～ 5.5 V（定电压输入）
- 输出电压（Vout）：5 V（隔离非稳压输出）
- 输出通道数：1 路
- 输出功率：250 mW
- 最大输出电流：50 mA
- 最大容性负载：2400 µF
- 转换效率：典型约 76%，在最佳工况下可达 91%（视负载与环境而异）
- 隔离耐压：1500 Vrms（1 min），3000 VDC（1 s）
- 开关频率：100 kHz
- 纹波与噪声：约 30 mVp-p
- 空载功耗：典型 0.02 W
- 工作温度：-40 ℃ ～ +85 ℃
- 外形尺寸（封装）：SIP，11.5 × 6 × 10 mm
三、保护与可靠性特性
- 短路保护：发生输出短路时模块限制输出并保护自身，避免损坏；
- 自动故障恢复：短路或异常消失后自动恢复工作，无需人工复位；
- 过热保护：温度异常升高时采取限流或关断保护，防止长期损坏。
这些保护机制提升了模块在复杂现场环境下的可靠性与可维护性。
四、典型应用场景
- 工业控制与传感器隔离电源（数据采集前端、隔离 I/O）
- 通讯接口与总线隔离（如 CAN、RS-485 的隔离供电）
- 模拟信号处理与 ADC 前端隔离，减少地环路干扰
- 低功耗便携设备、辅助电源或隔离逻辑供电场合
五、设计与使用建议
- 由于为“非稳压输出”，在对精度要求较高的负载侧建议配合 LDO 或稳压器使用，以获得更稳定的电压。
- 输出侧若需更低纹波，可外接低 ESR 电容或 LC 滤波，但要注意最大容性负载 2400 µF 的限制，避免启动异常。
- 输入端应加入合适的去耦电容，尽量靠近模块引脚布置，以抑制开关干扰。
- 输出与输入地要保持隔离，走线避免交叉敏感电路，必要时在隔离两侧增加共模滤波器。
- 考虑到工作温度范围，满载情况下高温环境会影响效率与寿命，建议留有散热空间并评估热闭塞。
六、包装与型号信息
- 品牌：YLPTEC（易川）
- 型号：B0505S-W2R2
- 封装形式：SIP（11.5 × 6 mm），高度 10 mm
- 适合批量贴片与手工焊接两种组装方式。
总结：B0505S-W2R2 以体积小、隔离等级高、低空载功耗与多重保护为特点，适合对隔离、空间与可靠性有要求的低功率电源设计场合。选择时请结合负载稳定性、纹波容忍度及温升条件进行评估。若需更高输出精度或更大功率，应考虑外部稳压或更高功率的模块。

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.
