LD03-23B05R2P 产品概述

一、产品简介

LD03-23B05R2P 是 YLPTEC(易川) 推出的高可靠性、全球输入范围的 AC/DC-DC 开关电源模块。该模块支持 85VAC305VAC 宽电压交流输入,同时兼容 120V432V 直流输入,单路 5V 输出,最大输出功率 3W。体积小、封装为 DIP-4,适合空间受限的板上电源方案,广泛用于工业控制、电器、智能家居与办公设备等需要安全隔离的小功率场合。

二、主要技术参数

  • 转换类型:AC/DC-DC(交直流两用)
  • 输入电压:85VAC305VAC;直流 120V432V
  • 输出通道数:1 路
  • 输出电压:5V,精度 ±5%
  • 输出电流(最大):600mA
  • 输出功率:3W
  • 空载静态功耗:0.1W(典型)
  • 转换效率:约 71%
  • 纹波噪声:80mVp-p(典型)
  • 最大容性负载:1000µF
  • 隔离耐压:4kV Vrms
  • 开关频率:65kHz
  • 尺寸(L×W×H):37.5mm × 18.5mm × 13.5mm
  • 封装:DIP-4

三、功能与保护

LD03-23B05R2P 具备完善的自保护功能,保证长期稳定运行与系统安全:

  • 过热保护:温升异常时限制或关断输出,故障自动恢复
  • 过流保护:过载时进入限流或保护状态,避免损坏模块与负载
  • 短路保护:短路出现时模块保护并在故障解除后自恢复
    以上保护均为自动恢复型,便于系统在瞬时异常后恢复工作,减少人工干预。

四、机械特性与封装

模块采用 DIP-4 插入式封装,尺寸 37.5×18.5×13.5mm,便于通过孔安装和批量装配。4kV 的基本隔离等级满足多数工业与民用应用的安全隔离要求。因模块为高频开关结构,安装时应保证周围有适当空气流通空间以利散热。

五、典型应用场景

  • 工业控制与自动化设备的隔离电源
  • 办公设备、监控模块、传感器供电
  • 智能家具与家电小功率电子模块
  • 各类需要从高压直流/交流获取低压稳定电源的场合

六、使用建议与注意事项

  • 输入端应加适当的滤波与保护器件(熔断器、浪涌抑制器)以提高系统整机可靠性。
  • 输出端若并联较大电容(接近 1000µF)或电感性负载,建议评估启动冲击与稳态纹波影响。
  • 模块效率约 71%,在高负载或高环境温度下应注意散热,必要时增加通风或金属散热体并适当降额使用。
  • 保持输入输出端与其它高电压回路良好绝缘并满足爬电距离规范,保证人员与设备安全。
  • 在潮湿或有腐蚀性气体环境中,应采取防护措施或选用专用防护外壳。

总结:LD03-23B05R2P 以其全球宽输入、双用电源特性、全面的保护功能与小巧封装,为需要安全隔离、稳定 5V 输出的多种小功率应用提供了可靠、经济的解决方案。如需更详细的电气性能曲线、典型应用电路或环境测试报告,可联系 YLPTEC(易川) 技术支持获取。

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.

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
