B2405XT-2WR3 产品概述

一、产品简介

B2405XT-2WR3 是 YLPTEC(易川)推出的一款高可靠性、板上安装的隔离式直流-直流转换器。该器件为单通道输出、非稳压型隔离模块,额定输出功率 2W,输出电压 5V、最大输出电流 600mA,专为板级电源系统中需要与输入电源电气隔离的场合设计。体积小(12.7 × 11.2 × 7.25 mm)、效率高(83%),并带有短路保护与自动恢复功能,适用于数字电路、低频模拟电路、继电器驱动等多种应用。

二、主要技术参数

  • 品牌 / 型号:YLPTEC(易川) / B2405XT-2WR3
  • 输入电压范围:21.6V ~ 26.4V
  • 输出电压:5V(非稳压型)
  • 输出功率:2W(最大)
  • 输出电流:最大 600mA
  • 转换效率:典型 83%
  • 隔离电压:1.5kV RMS(通常对应工频耐压等级,可满足常见≤3000VDC等效要求)
  • 最大容性负载:2400µF
  • 输出纹波噪声:50 mV p-p
  • 开关频率:450 kHz
  • 静态电流(空载):5 mA
  • 工作温度:-50 ℃ ~ +115 ℃
  • 保护功能:短路保护、自动故障恢复
  • 封装 / 尺寸:SMD-5P,12.7 × 11.2 × 7.25 mm
  • 稳压类型:非稳压型(输出会随输入电压与负载变化)

三、功能特点与注意事项

  • 隔离安全:模块提供输入与输出之间的电气隔离,适合需要隔离干扰、地回路切断或安全隔离的设计。
  • 非稳压输出:本产品为非稳压型,输出电压会随输入电压及负载变化而变化,建议输入电源在 ±10%Vin 范围内稳定,若需更精确的输出请在模块后加稳压或采用后级稳压器。
  • 保护与可靠性:具备短路保护并具备自动恢复功能,发生短路或过载后模块会自动进入保护状态并在故障解除后恢复输出,适合对可靠性有要求的板上应用。
  • 低功耗与热管理:在 83% 效率下,满载时功耗约 0.4 W(2W 输出对应约 2.41W 输入),需考虑板级散热与周围器件布局。
  • 负载容错:可驱动较大的旁路/滤波电容(最大容性负载 2400µF),便于降低输出纹波,但过大容性负载可能影响瞬态响应,布局时应注意。

四、典型应用场景

  • 纯数字电路及隔离逻辑电源(微控制器、通信接口隔离电源)
  • 低频模拟电路或测量前端的隔离供电(对噪声敏感但对稳压要求不高的场合)
  • 继电器、光耦或小功率驱动电路的隔离电源
  • 板上多电源系统中需要产生与总线电源隔离的辅助电压

五、设计与选型建议

  • 输入要求稳定:为保证输出在允许范围内,应提供稳定的输入电源,参考给定的 21.6V–26.4V 范围,并保持输入波动在 ±10% 以内。
  • 输出滤波:推荐在输出端并联低 ESR 电解电容与陶瓷电容以抑制纹波和瞬态噪声,但总容性负载不超过 2400µF。
  • 布局注意:尽量缩短输入/输出走线,良好接地,避免大面积铜箔靠近高频开关元件以减小 EMI。
  • 热管理:满载时有一定功耗发热,若在高温环境或连续满载工作,应评估PCB散热或增加导热措施。

B2405XT-2WR3 以其小体积、隔离性能与自动保护机制,适合对隔离、可靠性和板级集成度有要求的工程应用,是常见的板上隔离电源方案选择。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
