QA15115R2 隔离电源模块(YLPTEC 易川) — 产品概述

一、产品简介

QA15115R2 是 YLPTEC(易川)推出的一款高密度双通道隔离 DC‑DC 电源模块,封装为 SIP‑5(尺寸 19.5 × 9.8 × 12.5 mm)。模块设计用于在紧凑空间内提供稳定隔离电源:双输出(+15V 与 −2.5V),总输出功率 1.75W,适合为模拟前端、隔离信号调理及通信接口等提供独立电源。

二、主要电气参数

  • 输入电压范围:13.5 V ~ 16.5 V(典型车载/工业母线兼容)
  • 输出:双通道,Vout = +15V 与 −2.5V
  • 总输出功率:1.75 W(双路合计)
  • 单通道最大输出电流:100 mA(每通道)
  • 转换效率:78%(典型)
  • 静态电流(空载):17 mA
  • 纹波噪声:60 mVp‑p(典型)
  • 开关频率:85 kHz
  • 最大容性负载:220 μF(每路)
  • 隔离耐压(Vrms):3500 V
  • 工作温度:−40 ℃ ~ +105 ℃

三、保护与可靠性

  • 短路保护:模块具备短路保护并支持自动故障恢复(自动重启),便于在异常负载或突发短路时保护模块与系统负载。
  • 宽温设计及高耐压隔离:−40 ℃~+105 ℃工作范围与 3.5 kVrms 隔离耐压,满足工业级与部分车载应用的环境与安全要求。
  • 小封装、高密度:SIP‑5 结构适合批量装配,长期可靠性需参考实际散热和工作点选择。

四、热设计与 PCB 布局建议

  • 损耗估算:在最大输出条件下,输入功率约为 1.75W / 0.78 ≈ 2.24W,模块自身热耗约 0.49W(≈0.5W)。在小型 SIP 封装中需注意散热管理。
  • 布局要点:输入侧和输出侧走线尽量短、粗;输入侧靠近模块放置低 ESR 去耦电容(建议 10–100 μF);输出侧按说明放置容性负载(每路≤220 μF),并并联适当的陶瓷去耦以降低高频纹波。
  • 隔离区处理:在 PCB 上保证足够的爬电距离与空气间隙,隔离面尽量开孔或保留清洁区域以提升耐压性能。避免在隔离边缘走高速信号或散热铜箔影响击穿性能。

五、典型应用场景

  • 工业控制与自动化:为隔离放大器、数据采集前端、传感器供电;
  • 通信接口隔离:为 RS‑232/RS‑485、CAN 等隔离收发器提供独立电源;
  • 仪器仪表:为精密模拟电路提供独立 ± 电压或正负混合电源(本模块为 +15V 与 −2.5V);
  • 车载电子与便携电源系统:在符合输入范围的场景下可直接对接车载电源总线(注意车载浪涌与瞬态抑制)。

六、使用注意事项

  • 输出电流与容量:建议不超过每通道 100 mA,且每路容性负载不超过 220 μF;过大容性负载可能影响启动与稳定性。
  • 隔离与安全:3500 Vrms 为工频耐压测试等级,具体系统设计时应结合是否需要加强绝缘或满足更高的安全标准(如机电安全规范)进行评估。
  • EMI 与滤波:85 kHz 开关频率带来中频开关噪声,必要时在输入/输出侧添加滤波与共模抑制网络以满足 EMC 要求。
  • 环境与老化:高温时模块效率略降且热耗增加,应在高温工况下进行功率与温升复核并考虑降额使用。

QA15115R2 以其小体积、多路隔离输出与自动恢复保护特性,适合在空间受限且需可靠隔离电源的工业与通信系统中使用。若需针对具体拓扑的参考电路或 PCB 布局图,可提供进一步的应用指导与建议。

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
