YLPTEC B2403S-1WR3 1W隔离降压DC-DC转换器产品概述

一、产品定位与核心价值

YLPTEC B2403S-1WR3是一款专为工业控制、通信设备、传感器节点等场景打造的小功率隔离降压DC-DC转换器,核心解决24V直流电源(21.6~26.4V波动范围)向3.3V低压逻辑电路供电的问题,同时通过1.5kVrms隔离保障高低压侧电气安全,适配宽温、紧凑安装等严苛环境需求,是替代传统线性稳压+隔离方案的高性价比选择。

二、关键参数总览

类别 具体参数 输入特性 工作电压:21.6~26.4V DC(24V nominal ±10%,匹配工业电源常规波动);空载输入电流:8mA 输出特性 输出电压:3.3V DC;最大输出电流:303mA(1W额定功率);纹波噪声:30mVp-p 电气性能 转换效率:84%;隔离电压:1.5kVrms(1分钟);开关频率:260kHz 可靠性 短路保护(自动恢复);工作温度:-40℃~+105℃;最大容性负载:2400uF 物理特性 封装:SIP-4插针式;尺寸:11.6mm(长)×6mm(宽)×10.16mm(高);重量:约2g

三、核心性能优势

1. 宽输入电压适配工业电源波动

输入电压覆盖21.6~26.4V,精准匹配24V工业电源的**±10%常规波动范围**,无需额外稳压电路即可稳定工作,降低系统设计复杂度,避免因电源波动导致的输出异常。

2. 1.5kVrms高隔离保障系统安全

隔离电压达到1.5kVrms(满足GB/T 13070-2012电气隔离标准),可有效阻断高低压侧的电气干扰:

  • 防止高压侧噪声(如电机、继电器开关噪声)串入低压逻辑电路(MCU、ADC等);
  • 避免低压侧故障(如短路)影响高压电源,提升系统抗干扰能力与安全性。

3. 小体积高密度设计易集成

采用SIP-4插针封装,尺寸仅11.6×6×10.16mm,比传统DIP封装模块体积缩小约30%,适合紧凑PCB布局(如PLC输入输出模块、小型传感器节点);1W功率无明显温升,无需额外散热片即可稳定工作。

4. 宽温工作满足严苛环境

工作温度范围-40℃~+105℃,覆盖工业级环境(户外控制柜、车载电子)与部分高温场景,无需降额使用,可靠性符合IEC 60068-2-1(低温)、IEC 60068-2-2(高温)等环境测试标准。

5. 多重保护提升可靠性

  • 内置短路保护功能:负载短路时自动切断输出,故障排除后自动恢复,避免模块损坏;
  • 最大容性负载2400uF:兼容后端滤波电容需求,减少输出纹波,简化电路设计。

6. 低纹波噪声适合敏感电路

输出纹波噪声仅30mVp-p(典型值),无需额外滤波电路即可满足MCU、传感器、ADC等对纹波敏感的电路供电要求,降低系统噪声干扰。

四、典型应用场景

  1. 工业自动化:PLC输入输出模块、远程IO单元(24V转3.3V给逻辑芯片供电);
  2. 传感器节点:户外温度/压力传感器(宽温适配,隔离防止现场电磁干扰);
  3. 通信设备:基站辅助电源、光纤收发器(小体积集成,低纹波保障信号传输);
  4. 车载电子:车载辅助控制系统(-40~105℃宽温,1.5kV隔离保障安全);
  5. 医疗设备:小型监护仪辅助模块(隔离满足电气安全标准,低纹波保障信号精度)。

五、选型与使用注意事项

  1. 输入电压限制:避免输入电压超过26.4V(过压可能损坏模块),低于21.6V会导致输出电压不稳定;
  2. 输出电流限制:最大输出电流303mA,若负载电流超过此值,需降额使用(如负载250mA需保证环境温度≤85℃)或并联模块;
  3. 负载电容:后端容性负载不超过2400uF,避免开机冲击电流过大;
  4. 引脚顺序:SIP-4引脚通常为「1=Vin+、2=Vin-、3=Vout+、4=Vout-」,需参考官方datasheet确认后焊接;
  5. 散热建议:1W功率无强制散热需求,但+105℃环境需保证通风,避免密闭安装。

六、总结

YLPTEC B2403S-1WR3以宽输入适配、高隔离安全、小体积集成、宽温可靠为核心优势,精准匹配工业24V系统向3.3V低压电路供电的需求,可有效简化系统设计、提升设备可靠性,是工业控制、通信、传感器等领域的高性价比选择。
