YLPTEC(易川)QA151C 电源模块产品概述

YLPTEC(易川)QA151C是一款双输出隔离式DC-DC电源模块,专为12V系统(如车载、工业控制)设计,兼顾宽输入范围、高隔离等级与紧凑封装,可满足多场景下正负电源的同步输出需求。

一、产品核心定位与优势

QA151C针对“小功率、双路输出、宽环境适应性”的应用痛点优化,核心优势包括:

  1. 双路输出适配:同时提供-5V(低噪声偏置)与20V(中功率供电)两路输出,覆盖模拟电路与数字电路的复合需求;
  2. 宽输入电压范围:13.5~16.5V DC,兼容12V系统的正常波动(如车载13.8V±2V、工业12V电源±10%);
  3. 高隔离安全:3.5kV AC(rms)隔离电压,有效隔离前后级电路(强电/弱电、高压/低压),避免串扰与安全隐患;
  4. 工业级宽温:-40℃~+105℃工作温度,适应户外、车载等极端温差环境;
  5. 集成保护:内置短路保护,输出短路时自动切断负载,故障排除后自行恢复。

二、关键电气性能参数详解

1. 输入参数

  • 工作电压:13.5~16.5V DC(典型值13.8V,适配12V系统主流电压);
  • 输入纹波:无强制要求(前端可搭配小容量电容优化)。

2. 输出参数

  • 通道1(负电源):Vout=-5V DC,最大输出电流40mA;
  • 通道2(正电源):Vout=20V DC,最大输出电流80mA;
  • 纹波噪声:60mVp-p(20MHz带宽,低纹波适合敏感电路);
  • 最大容性负载:220uF(单路/双路总负载,避免启动冲击)。

3. 效率与频率

  • 转换效率:75%(小功率隔离模块中属合理水平,降低散热压力);
  • 开关频率:95kHz(避开20kHz音频频段,减少电磁干扰)。

三、物理封装与尺寸规格

QA151C采用SIP-5引脚式封装,体积紧凑:

  • 尺寸:19.5mm(长)×9.8mm(宽)×12.5mm(高);
  • 封装优势:SIP-5便于PCB插件焊接,引脚间距符合工业标准,适合空间受限设备(如车载仪表盘、小型仪器);
  • 引脚定义:需参考官方 datasheet(通常含输入正、输入负、-5V输出、20V输出、公共地)。

四、安全与可靠性保障

  1. 电气隔离:3.5kV AC(rms)隔离电压,满足IEC 60950安全标准,适配医疗、工业等隔离要求高的场景;
  2. 短路保护:输出短路时自动进入保护状态,故障排除后自行恢复(无需手动复位);
  3. 宽温可靠性:经高低温循环测试,-40℃~+105℃范围内稳定工作,MTBF符合工业级要求;
  4. 抗干扰能力:95kHz开关频率避开音频与射频频段,减少EMI干扰,适配EMC严格设备。

五、典型应用场景

QA151C的特性使其适配多类场景:

  1. 车载电子:车载音响(-5V偏置、20V功放供电)、行车记录仪(辅助电源)、车载传感器;
  2. 工业控制:PLC I/O电源、工业传感器(正负电源)、小型工业仪器;
  3. 医疗设备:低功率医疗仪器(如小型监护仪、血糖仪,需隔离安全);
  4. 通信设备:小型基站辅助电源、光纤收发器电源;
  5. 仪器仪表:示波器、信号发生器的正负电源(-5V偏置、20V数字供电)。

六、应用注意事项

  1. 输入电压控制:避免超过16.5V(过压)或低于13.5V(欠压),可搭配TVS管优化;
  2. 负载限制:双路输出分别控制在最大电流以内(-5V≤40mA,20V≤80mA);
  3. 容性负载:后端总容性负载不超过220uF,注意启动冲击;
  4. 焊接规范:焊接温度≤260℃,单次时间≤10秒,避免损伤模块;
  5. 散热设计:满负载时保证通风,避免密闭空间(转换效率75%,存在少量热量);
  6. 绝缘要求:隔离应用时,前后级电路保持足够绝缘距离,符合安全标准。

QA151C凭借双路输出、宽温宽压、高隔离的特性,成为12V系统中小功率电源设计的优选方案,可简化电路布局,提升系统可靠性。

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
