B0505XT-1WR3 — 1W 隔离型 DC-DC 转换器 产品概述
一 产品概述
B0505XT-1WR3 是 YLPTEC（易川）推出的一款单通道、1W 输出功率的隔离型 DC-DC 转换器，输入电压范围 4.5V～5.5V，输出稳压 5V，针对体积受限且需电气隔离的小功率场景设计。模块已通过校验，适合工业控制、信号采集与通信等需要可靠隔离的小功率电源应用。
二 主要参数与性能
- 通道数：1；额定输出功率：1W（最大输出电流 200mA）
- 输入电压 Vin：4.5V～5.5V；输出电压 Vout：5V
- 转换效率：典型 82%；开关频率：220kHz
- 空载输入电流：3mA；输出纹波噪声：120mVp-p（典型）
- 最大容性负载：2400µF；隔离电压（Vrms）：1.5kV
- 特性：具备短路保护；工作温度范围：-40℃～+105℃
三 尺寸与封装
模块尺寸紧凑，长×宽×高：13.5mm × 11.1mm × 7.25mm，采用 SMD-5P 封装（封装尺寸 12.7mm × 8.3mm），适合表面贴装工艺，可在空间受限的 PCB 布局中方便集成。
四 典型应用
- 工业现场数据采集与信号隔离（破除地环路）
- 嵌入式系统与微控制器供电（USB 5V 取电后隔离）
- 通信设备、传感器模块的小功率供电与隔离保护
- 仪表与测量设备中对隔离、低噪声电源的需求场景
五 设计与使用建议
- 输入/输出端应靠近模块焊盘放置必要的去耦电容，降低纹波与电磁干扰。
- 对于对噪声敏感的负载，建议在输出端加 L-C 滤波或后级线性稳压以进一步降低纹波。
- 注意隔离区的爬电距离与电气间隙要求，PCB 布局时确保满足 1.5kVrms 的隔离设计规范。
- 在高温条件下按规格书对输出电流进行适当降额，留出热设计裕量；短路保护可防止异常损坏，具体恢复行为请参阅厂家资料。
- 若系统对 EMI 有严格要求，可在输入侧增加共模滤波器并优化接地回路。
六 选型要点
选择 B0505XT-1WR3 的主要理由包括：小型 SMD 封装便于密集布板、5V 输入/输出适配 USB 或单电源系统、1.5kV 隔离满足一般工业和通信隔离需求、较高效率与低空载电流适合能耗敏感设计。若需更高输出电流或更大隔离等级，应参考同系列或更高规格产品。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
