B1209S-1WR3 降压型DC-DC电源模块产品概述

B1209S-1WR3是YLPTEC(易川)推出的小功率隔离降压型DC-DC电源模块,专为12V系统(含波动范围)向9V低功耗器件供电设计,具备宽温适应性、电气隔离、短路保护等核心特性,可广泛应用于工业控制、车载电子、通信设备等场景。

一、核心功能与典型应用场景

该模块属于单通道降压转换器,核心功能是将10.8~13.2V的输入电压稳定转换为9V输出,最大输出功率1W(对应输出电流111mA),适配低功耗核心器件的供电需求,典型应用包括:

  1. 工业传感器供电:如温度、压力传感器的隔离供电,避免现场电磁干扰影响采集精度;
  2. 车载电子辅助模块:如仪表盘背光、小型控制单元的12V转9V供电,适应车载环境的温度波动;
  3. 通信设备接口电路:如低功耗无线模块、串口转换器的隔离电源,阻断设备间的共地干扰。

二、关键电气参数详解

模块的电气参数针对小功率隔离场景做了优化,核心参数如下:

  • 输入输出范围:输入电压覆盖10.8~13.2V(12V系统±10%波动),无需额外稳压即可直接接入;输出电压稳定在9V,最大输出电流111mA(功率1W),满足多数低功耗MCU、传感器的供电需求;
  • 转换效率:89%的转换效率在同功率隔离模块中处于较高水平,可有效减少模块自身发热,适配紧凑安装空间;
  • 纹波噪声:输出纹波噪声仅30mVp-p,远低于多数模拟器件的噪声耐受阈值,适合高精度ADC、模拟传感器等对电源纯净度要求高的负载;
  • 开关频率:260kHz高频开关设计,既缩小了模块体积,又便于EMI(电磁干扰)控制,符合工业设备的电磁兼容要求;
  • 容性负载能力:最大可带1000uF容性负载,适应后级电路含大电容滤波的场景,输出稳定性更高。

三、可靠性与防护特性

模块内置多重防护设计,提升系统运行可靠性:

  • 短路保护:输出端短路时自动切断电源,故障排除后可自动恢复,避免模块损坏及负载烧毁;
  • 电气隔离:1.5kVrms的隔离电压可有效阻断输入输出侧的电气连接,防止共地干扰、高压串扰,适配跨电压域应用;
  • 宽温工作:-40℃至+105℃的工作温度范围,覆盖工业现场的极端环境(如低温存储、高温车间)及车载电子的高低温要求,无需额外散热设计。

四、封装与安装适应性

采用SIP-4单列直插封装,具有以下优势:

  • 体积紧凑:符合小功率模块的空间需求,可直接插件至PCB板,或用于面包板测试;
  • 引脚布局:遵循标准SIP-4引脚定义(通常为Vin+、Vin-、Vout+、Vout-),便于快速集成至现有电路;
  • 安装便捷:无需复杂焊接工艺,适合批量生产或原型开发。

总结

B1209S-1WR3作为一款小功率隔离降压模块,凭借宽温适应性、低纹波、短路保护及紧凑封装等特性,成为12V系统向9V低功耗器件供电的优选方案,可有效提升工业、车载等场景下的供电可靠性与系统稳定性。

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
