B0512S-1WR3 产品概述
一、产品简介
B0512S-1WR3 是 YLPTEC(易川) 出品的一款升压型单通道直流-直流模块，额定输出功率 1W，适配输入电压 4.5V～5.5V，可稳定输出 12V 电压，最高输出电流 84mA。模块为插件（通孔）封装，体积小巧（11.6mm × 6mm × 10.16mm），具有 1.5kVrms 隔离能力与短路保护功能，适合在工业、通信与测量等对小功率隔离升压有需求的场合使用。描述校验通过。
二、主要性能参数
- 功能类型：升压型（Boost）
- 通道数：1
- 输入电压 Vin：4.5V ～ 5.5V
- 输出电压 Vout：12V
- 输出功率：1W（最大）
- 输出电流：最大 84mA
- 转换效率：典型 89%（满载时）
- 开关频率：270kHz
- 空载输入电流：8mA
- 纹波噪声：30mVp-p（典型）
- 最大容性负载：560µF
- 隔离电压 Vrms：1.5kV
- 保护特性：短路保护
- 工作温度：-40℃ ～ +105℃
- 封装形式：插件（通孔）
- 尺寸：长 11.6mm × 宽 6mm × 高 10.16mm
三、典型应用场景
- 从 USB 5V 提升为 12V，为小功率传感器、模拟前端、偏置电源或低功率驱动电路供电；
- 工业控制与数据采集系统中的隔离供电，防止地环路与干扰传递；
- 通信设备的局部升压与系统电平转换；
- 测试与测量设备中为放大器或参考电路提供稳定小功率 12V 源；
- 其他对 1W 级隔离升压有要求的嵌入式或模块化系统。
四、使用建议与注意事项
- 输入侧建议靠近模块放置去耦电容（低 ESR 型电容），以抑制输入纹波并保证稳定；
- 输出侧若供电敏感模拟电路，可在模块输出并联适当的滤波网络（LC 或 RC）以进一步降低 30mVp-p 纹波；
- 最大容性负载不超过 560µF，过大容性负载可能影响启动行为与稳定性；
- 模块具短路保护，但不建议长时间短路工作；发生短路时应查明原因并排除后再恢复使用；
- 89% 的转换效率意味着在满载时有约 0.12W 的功耗（1W 输出时），应留意散热条件：保证周围有足够空气流通，避免长期高温运行；
- 开关频率 270kHz，可能产生高频电磁干扰（EMI），布局时应注意走线最短化、屏蔽与接地处理；
- 空载输入电流为 8mA，系统待机功耗评估时应计入；
- 工作温度范围宽（-40～+105℃），但应按具体应用场景考虑元件老化与环境应力，必要时做适当的热设计与降额使用。
五、可靠性与检验
模块通过基本校验，具备 1.5kVrms 隔离能力，可用于需要功能隔离的应用。短路保护提高了系统容错性与安全性。建议在生产前进行整机电气和热测试验证，包括长期温升、启动-停止循环以及在目标负载与环境下的稳定性测试。
六、选型与采购建议
在选型时，请确认输入源稳定性（5V 供电是否允许瞬态低压）、所需输出滤波等级与峰值负载能力；若系统对噪声与纹波要求更高，可考虑配套滤波或选择低噪型模块。模块为插件封装，便于手工或波峰焊接组装，适合批量生产与维修替换。购买时请向 YLPTEC(易川) 或授权代理商确认最新数据手册与可用性，以确保参数与性能满足最终应用需求。

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.
