QA241 双路隔离式 DC-DC 模块电源(YLPTEC 易川)产品概述

一、产品简介

QA241 是一款专门为 IGBT 驱动器设计的塑封 SIP-5 DC-DC 模块,采用非对称双路输出拓扑,可为驱动电路提供 -8V 与 +15V 两路隔离电源。模块致力于在保证隔离与可靠性的同时,尽可能减小 IGBT 驱动损耗,适合工业级驱动与电力电子设备使用。

二、主要电气参数与性能

  • 输入电压:22.8V ~ 25.2V(典型 24V 总线)
  • 输出:-8V / +15V(双路非对称输出)
  • 输出电流(最大):120mA(每路)
  • 最大容性负载:1000µF
  • 隔离电压:3000Vrms
  • 转换效率:典型 81%,峰值可达 85%
  • 开关频率:200kHz
  • 静态电流(无负载):30mA
  • 输出纹波噪声:200mVp-p(典型)

三、保护与可靠性特性

QA241 提供持续短路保护与自动故障恢复功能:在输出短路或过载时进入限制或关断状态,故障解除后可自动恢复工作,便于封装式系统长期运行。模块工作温度范围宽(-40℃ ~ +105℃),并且设计有超小隔离电容以降低高 dv/dt 条件下的耦合干扰,适合电机驱动与高频逆变环境。

四、机械与封装

  • 尺寸:19.5mm × 9.8mm × 12.5mm(L×W×H)
  • 封装:SIP-5 国际标准引脚,便于穿孔安装与批量生产更换。模块为塑封结构,适合严苛工业环境,但建议在高温场合注意散热与周边元件布局。

五、典型应用

  • IGBT 驱动器电源(主推)
  • 通用变频器与交流伺服驱动系统
  • 电焊机控制板、UPS 辅助电源
  • 其他要求隔离、双极性或非对称输出的小功率驱动场合

六、选型与使用建议

  • 输入端应使用低 ESR 电解或陶瓷电容以抑制总线纹波,减小输入尖峰;输出端建议并联陶瓷 + 电解以兼顾高频与大电容需求。
  • 最大容性负载不得超过 1000µF;启动时注意大电容对输入冲击电流的影响,必要时加入软启动或限流措施。
  • PCB 布局时将输入/输出地短而粗引线,输出旁放置旁路电容以降低纹波。保持模块引脚附近无高频敏感信号,利用隔离优势确保控制逻辑安全。
  • 在高温或封闭空间内使用时,应评估热累积并根据应用适当降额运行。

七、注意事项

  • 虽具自动恢复短路保护,但频繁短路或长期过载会影响寿命,建议配合系统过流检测与排故策略。
  • 隔离标称 3000Vrms,实际应用中仍需遵守安全规范,保持适当爬电距离与绝缘处理。
  • 出于可靠性考虑,安装与焊接时参考 SIP-5 引脚规格与热应力限制,避免超温回流。

QA241 以其非对称双路输出、工业级温度范围与高隔离性能,成为变频器与 IGBT 驱动等电力电子系统中紧凑、可靠的辅助电源选择。

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
