IB1205S-W75R3 降压型DC-DC电源模块产品概述

IB1205S-W75R3是YLPTEC(易川) 推出的一款单通道隔离降压型DC-DC电源模块,专为12V系统(含波动范围)转换为5V小功率供电场景设计,具备电气隔离、短路保护等核心特性,可满足工业控制、物联网终端、小型通信设备等领域的紧凑化供电需求。

一、核心功能与目标应用场景

该模块为隔离降压型设计,核心功能是将11.4V~12.6V的输入电压(覆盖典型12V电源±5%的波动范围,如铅酸电池、12V适配器输出)转换为稳定的5V直流输出,最大输出电流200mA,额定输出功率750mW。

其目标应用场景包括但不限于:

  • 工业传感器节点(如温度、压力传感器的5V供电);
  • 小型物联网终端(如低功耗通信模块的电源转换);
  • 通信设备辅助电路(如12V系统下的5V控制电路供电);
  • 户外/车载小型设备(适应宽温环境)。

二、关键电气参数详解

2.1 输入输出特性

  • 输入电压范围:11.4V~12.6V DC,覆盖12V系统常见波动(如电池放电、适配器负载变化),无需额外稳压即可直接输入;
  • 输出电压:5V DC(标准数字电路/USB设备供电电压),精度满足多数小功率负载需求;
  • 最大输出电流:200mA,额定输出功率750mW(5V×200mA=1W,实际因效率损耗为750mW,输入功率约1W);
  • 最大容性负载:2400μF,支持输出端接大电容滤波,进一步降低纹波噪声,适配负载电容较大的电路(如含大容量电解电容的负载)。

2.2 效率与纹波

  • 转换效率:74%,小功率模块的典型效率水平,热耗较低(输入1W时热耗约0.26W),无需额外散热即可稳定工作;
  • 纹波噪声:30mVp-p(峰峰值),低纹波特性适合对电源噪声敏感的数字电路(如MCU、ADC等),避免噪声干扰信号采集或逻辑运算。

2.3 隔离特性

  • 隔离电压:1.5kVrms(交流有效值),具备电气隔离能力,可有效阻断输入输出端的共模干扰耦合,提升系统EMC性能,同时防止输入侧故障(如高压尖峰)损坏输出负载电路,增强系统安全性。

三、机械与环境适应性

3.1 封装与尺寸

  • 封装形式:SIP(单列直插式),安装方式灵活,可直接焊接于PCB板,或通过插座实现插拔更换,适合批量生产或后期维护;
  • 外形尺寸:11.5mm(长)×6mm(宽)×10mm(高),紧凑体积适配小型化设备的内部空间布局,满足对尺寸敏感的应用需求。

3.2 工作温度范围

  • 工作温度:-40℃~+85℃,覆盖工业级环境温度范围,可适应户外低温(如北方冬季)、车间高温(如设备运行发热环境)等复杂场景,无需额外温控措施。

3.3 开关频率

  • 开关频率:100kHz,中频范围设计兼顾效率与EMI性能:既避免高频(如MHz级)带来的电磁干扰问题,也无需采用超小型化的电感电容(降低成本与设计难度)。

四、保护与可靠性设计

该模块内置短路保护功能:当输出端因意外(如导线短路、负载故障)导致短路时,模块自动启动保护机制(限制输出电流或切断输出),防止模块内部元件因过流损坏,同时避免故障扩散至输入电源或其他电路,提升系统整体可靠性。

五、总结

IB1205S-W75R3是一款针对12V转5V小功率供电的高性价比隔离降压模块,其紧凑尺寸、宽温适应性、电气隔离与短路保护特性,使其成为工业控制、物联网、通信等领域小型设备的理想供电解决方案,可有效简化电源设计流程,提升系统稳定性。

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
