URB2405YMD-20WR3 产品概述
URB2405YMD-20WR3 是 YLPTEC(易川) 推出的一款高密度单通道降压型直流/DC–DC 转换器，额定输出功率 20W，专为工业级、通信及嵌入式系统的稳压供电设计，体积小、效率高并带有短路保护等实用保护功能，适用于要求高可靠性与长寿命的场合。
一、核心参数概览
- 功能类型：降压型 (Buck)
- 通道数：1
- 输出功率：20W
- 输入电压范围：9V ~ 36V
- 输出电压：5V
- 输出电流（最大）：4A
- 转换效率：90%（典型）
- 开关频率：250kHz
- 纹波噪声：50mVp-p（典型）
- 空载输入电流：25mA
- 最大容性负载：10000µF
- 隔离电压：1.5kVrms
- 工作温度：-40℃ ~ +85℃
- 外形尺寸（封装）：DIP，25.4 × 25.4 × 11.8 mm
二、性能与效率说明
该模块在额定负载下的典型转换效率可达约 90%，输出 20W 时输入功率约为 22.2W。以最小输入电压 9V 计算，满载输入电流约为 2.5A；以最大输入电压 36V 计算，满载输入电流约为 0.62A（均为近似值，实际值随效率波动）。开关频率为 250kHz，可在尺寸与EMI之间取得良好折衷。
三、保护与可靠性特点
- 短路保护：提供对输出短路或严重过流状况的可靠防护，提升系统安全性。
- 低功耗待机：空载输入电流仅 25mA，有利于低功耗应用场景。
- 宽温设计：-40℃ 至 +85℃ 的工业级温度范围，适合苛刻环境工作。
- 隔离能力：1.5kVrms 隔离电压，适用于需一定隔离等级的系统（请根据具体应用验证所需认证与接地策略）。
四、机械与布局注意事项
模块采用标准 25.4 × 25.4 mm DIP 封装，厚度 11.8 mm，便于插装与焊接到标准化板位。建议在布局时：
- 输入/输出端尽量短且粗，减少寄生阻抗与纹波。
- 输出端并联适量低ESR电容以满足瞬态响应与容性负载需求，最大支持 10000µF。
- 考虑模块散热需求，必要时在 PCB 下方或附近预留散热铜箔并保证空气流通。
五、典型应用场景
- 工业控制与PLC 电源模块
- 网络与通信设备的辅助供电（如路由器、交换机控制电路）
- 嵌入式系统与单板计算设备
- 仪器仪表与电池供电系统（作为降压稳压模块）
六、选型与使用建议
- 若系统需更高隔离等级或医疗/安规认证，请确认模块证书或选择专门认证产品。
- 对于高容性启动负载，建议在启动回路中加入限流或渐进上电方案以降低冲击电流。
- 在高温或近满载应用下，注意热降额设计，必要时增加散热辅助件或降低工作温度。
七、总结
URB2405YMD-20WR3 以其紧凑的 DIP 尺寸、90% 典型效率、宽输入电压和工业级工作温度，适合作为 5V/4A 稳压电源解决方案。结合短路保护、低空载功耗和高容性负载支持，能满足多种工业与嵌入式应用的可靠供电需求。若需进一步电气参数曲线、引脚定义或典型应用电路图，请提供具体需求以便提供更详细的支持。

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.
