B2403S-3WR2 3W降压型DC-DC电源模块产品概述

B2403S-3WR2是YLPTEC(易川)推出的1通道非隔离降压型DC-DC电源模块,专为24V系列输入的3.3V低压输出场景设计,额定功率3W,兼具宽输入范围、高转换效率、工业级可靠性等特性,适用于工业控制、物联网终端、通信设备等场景的高效供电需求。

一、核心功能与应用定位

该模块采用降压拓扑结构,核心功能是将21.6V~26.4V输入电压(覆盖24V电源±10%波动)高效转换为3.3V稳定输出,满足小功率数字电路、传感器等负载的供电需求。其设计定位偏向工业级紧凑场景:

  • 适配工业现场常见的24V电源波动;
  • 小体积SIP封装适合设备内部紧凑布局;
  • 宽温与隔离特性可应对 harsh 环境干扰。

二、关键电气参数详解

2.1 输入输出特性

  • 输入电压范围:21.6V~26.4V(兼容24V电源的正常波动,工业现场兼容性强);
  • 输出电压:3.3V(稳定输出,满足多数3.3V数字电路的供电要求);
  • 最大输出电流:909mA(3W/3.3V≈909mA,覆盖多数小功率负载的电流需求);
  • 最大容性负载:2400uF(支持大容量负载电容,抑制负载突变时的电压波动,提升系统稳定性)。

2.2 效率与功耗

  • 转换效率:82%(3W功率下保持较高效率,减少模块发热,延长使用寿命);
  • 空载输入电流:4mA(低待机功耗,适合长期待机的物联网设备,降低能源消耗)。

2.3 纹波与噪声

  • 纹波噪声:80mVp-p(输出纹波控制在较低水平,避免干扰数字电路的信号传输)。

2.4 隔离与保护

  • 隔离电压:1.5kVrms(输入输出间电气隔离,有效隔离地环路干扰,提升系统抗干扰能力);
  • 短路保护:内置短路保护功能,负载短路时自动切断输出,故障排除后可恢复,保护模块与后端负载。

2.5 工作特性

  • 工作温度范围:-40℃~+85℃(工业级宽温设计,适应户外、高低温车间等极端环境);
  • 开关频率:250kHz(高频开关设计,减小电感电容体积,进一步压缩模块尺寸)。

三、封装与物理特性

  • 封装类型:SIP-4(单列直插式封装,4个插针引脚,焊接方便,PCB布局灵活);
  • 物理尺寸:长19.65mm×宽10.16mm×高7mm(小体积设计,可轻松集成到紧凑设备内部,节省空间)。

四、典型应用场景

B2403S-3WR2的参数特性使其适配多种场景:

  1. 工业自动化:PLC模块、传感器节点、工业相机的3.3V供电(宽温、隔离特性适配工业现场);
  2. 物联网终端:远程监测设备、低功耗网关的待机供电(低空载电流节省能源);
  3. 通信设备:小型基站、无线模块的电源转换(1.5kV隔离防干扰);
  4. 车载电子:车载终端的辅助供电(宽输入电压适配车载电源波动)。

五、可靠性与品牌优势

YLPTEC(易川)作为专业电源模块品牌,B2403S-3WR2经过高低温循环、振动冲击、绝缘耐压等工业级测试,确保长期稳定运行。内置短路保护、宽温设计等特性,进一步提升了产品的可靠性与使用寿命,是小功率24V转3.3V场景的高性价比选择。

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
