IB0503S-W75R3 直流-直流降压隔离电源模块产品概述

IB0503S-W75R3是**YLPTEC(易川)**推出的一款单通道降压型隔离电源模块,专为低功耗、小功率供电场景设计,兼具电气隔离安全与稳定输出特性,可满足工业、消费电子等多领域的供电需求。

一、核心功能与应用定位

该模块属于固定输出降压隔离模块,采用单通道设计,最大输出功率750mW,重点解决低功耗设备的“电源隔离+电压降压”双重需求:既通过电气隔离提升系统抗干扰能力与安全防护性,又将5V左右输入电压转换为3.3V稳定输出,适配主流MCU、传感器等核心器件的供电要求。

二、关键电气性能参数

1. 输入输出特性

  • 输入电压范围:4.75V~5.25V,覆盖常见5V系统的波动范围(如USB供电、5V开关电源输出),兼容性强;
  • 输出电压:固定3.3V,精度满足大多数数字/模拟电路的供电要求(典型误差可通过后级滤波进一步优化);
  • 输出能力:最大输出电流200mA,对应最大输出功率750mW(3.3V×227mA≈750mW),支持中小功率负载;
  • 容性负载兼容性:最大可带2400μF容性负载,无需额外设计复杂的输出滤波电路,简化系统布局。

2. 效率与纹波

  • 转换效率:68%(典型值),在小功率隔离模块中处于合理水平,工作时发热可控,无需额外散热设计;
  • 纹波噪声:30mVp-p(典型值),低纹波特性可避免对敏感模拟电路(如传感器信号采集)的干扰,提升系统稳定性;
  • 开关频率:100kHz(固定),中频设计兼顾效率与EMI(电磁干扰)控制,无需额外EMI滤波即可满足多数场景要求。

3. 隔离与安全

  • 隔离电压:1.5kVrms(交流有效值),满足基本电气隔离需求,可有效隔离输入输出端的噪声干扰,同时提升设备电气安全(如防止高压串入低压电路)。

三、物理封装与尺寸

该模块采用**SIP-4(单列直插4引脚)**封装,尺寸为11.5mm(长)×6mm(宽)×10mm(高),体积小巧紧凑,适合空间受限的PCB设计(如小型手持设备、嵌入式模块),直插式封装便于手工焊接与批量生产。

四、可靠性与保护设计

1. 工作温度范围

  • 宽温设计:-40℃~+85℃,可适应工业环境的低温、高温变化(如户外传感器节点、车载辅助设备),无需额外温控措施。

2. 保护功能

  • 短路保护:内置过流保护机制,输出端短路时自动切断或限制电流,避免模块损坏与负载烧毁;
  • 低功耗特性:待机或轻载时功耗低,适合电池供电设备(如便携式监测仪)的长续航需求。

五、典型应用场景

IB0503S-W75R3的特性使其适用于以下场景:

  1. 工业控制:小型PLC输入输出模块、传感器节点(如温度/压力传感器)的隔离供电;
  2. 消费电子:智能家居终端(如智能插座、传感器)、手持设备(如便携式检测仪)的电源转换;
  3. 通信设备:低功耗无线模块(如蓝牙、LoRa)的辅助隔离供电;
  4. 医疗电子:小型家用医疗设备(如血压计、血糖仪)的安全隔离供电(1.5kV隔离满足基本安全标准)。

六、产品优势总结

该模块的核心优势包括:

  • 隔离安全:1.5kVrms隔离电压,提升系统抗干扰与安全防护;
  • 小体积易集成:SIP-4封装+紧凑尺寸,适配空间受限场景;
  • 宽温可靠性:-40℃~+85℃工作范围,适应恶劣环境;
  • 低纹波稳定:30mVp-p纹波,适合敏感电路;
  • 输入兼容性:覆盖5V系统波动,应用灵活。

IB0503S-W75R3作为一款高性价比的小功率隔离降压模块,可快速满足低功耗设备的电源隔离与降压需求,降低系统设计复杂度。

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
