QA151C3 双输出隔离式DC-DC模块 产品概述

QA151C3 是 YLPTEC(易川) 推出的一款高可靠性、双输出隔离式 DC-DC 电源模块,适用于工业、通信、测控等需要隔离电源与双电压轨的应用场景。模块采用 SIP-5 封装,体积小、效率高、具有短路保护与自动恢复功能,支持较宽的工作温度范围,适合嵌入式与工业级系统设计。

一、核心参数概览

  • 输入电压范围:13.5 V ~ 16.5 V(典型 15 V)
  • 输出通道数:2(双轨输出:-4 V 与 +15 V)
  • 输出电流(每通道最大):100 mA
  • 转换效率:典型 82%
  • 隔离电压(Vrms):3.5 kV
  • 最大容性负载:220 μF(对每路输出)
  • 纹波与噪声:80 mV p-p
  • 开关频率:100 kHz
  • 静态电流(无负载):15 mA
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 保护特性:短路保护、自动故障恢复
  • 机械尺寸(SIP-5):长 19.5 mm × 宽 9.8 mm × 高 12.5 mm

二、功能与保护特性

  • 双路隔离输出:模块提供 -4 V 与 +15 V 两路输出,适合需要双极电源或数字/模拟隔离供电的场合。两路输出均来自同一隔离变换器,便于系统布局。
  • 短路保护与自动恢复:当输出短路或过载发生时,模块进入保护状态并在故障消除后自动恢复工作,降低系统维护复杂度。
  • 高隔离能力:3.5 kVrms 隔离电压可有效隔离高噪声或高电位侧,增强系统安全性与抗干扰能力。

三、电气与热性能要点

  • 效率与热耗:典型转换效率 82%;在满载(两路各 100 mA)情况下,总输出功率约 1.9 W,估算输入功率约 2.32 W,模块自身功耗约 0.42 W,需在封装和 PCB 布局中考虑散热路径以维持长时稳定工作。
  • 纹波噪声:80 mV p-p,适合一般模拟/数字电路的电源需求;对超低噪声要求的前端电路建议在输出处增加滤波或线性后级调节。
  • 容性负载容忍:每路最大允许容性负载可达 220 μF,有利于实现稳压与瞬态响应,但并非无限制,建议按照应用场景合理选型与测试。

四、典型应用场景

  • 工业控制与传感器前端:为隔离采样、差分放大器或隔离模数转换器提供稳定双极电源。
  • 通信设备与基站辅助电源:在 12 V 系统(蓄电池或车载 13.5–16.5 V)下直接供电,提供本地隔离输出。
  • 医疗与测试测量设备(非直接替代医疗隔离认证):用于需要隔离防护的测量环节(实际使用时需结合认证需求)。
  • 仪器仪表与便携设备:体积小、功率适中,适合紧凑型电路板设计。

五、设计与使用建议

  • 输入旁路与滤波:建议在输入端靠近模块引脚并并联 10 μF(低 ESR)和 0.1 μF 陶瓷去耦电容,以抑制输入瞬态和开关噪声。
  • 输出去耦与滤波:在每路输出端靠近引脚放置 0.1 μF 陶瓷与适当的电解/固态电容(依据最大 220 μF 限制)组合,改善瞬态响应并降低纹波。
  • PCB 布局:保持高频回路短且宽,输入/输出地线布线分离(模块隔离侧视为浮地),尽量缩短电感性连线,避免长导线引入辐射与噪声。
  • 散热:在高环境温度或接近额定输出的连续工作情况下,保持周围空气对流或在 PCB 上预留散热铜箔以帮助热量传导。
  • EMC/滤波:因工作频率 100 kHz,注意对系统 EMI 的抑制,必要时在输入端加入共模电感或额外的滤波网络。

六、注意事项与可靠性

  • 隔离注意:3.5 kVrms 隔离是模块自身能力指标,具体在系统设计时仍需考虑爬电距离、绝缘材料与端子布局以满足整机安全标准。
  • 启动与长时运行:模块具自动故障恢复能力,但不建议在频繁故障条件下长期运行,应查明故障根源(短路或超载)以避免影响系统可靠性。
  • 温度影响:在低温启动与高温运行环境下,关注输出稳定性与热累积效应。模块额定工作温度覆盖 -40 ℃ 至 +105 ℃,适合宽温应用。

QA151C3 以其双输出、隔离特性与自动保护功能,为工业与通信等领域提供了一种体积小、效率较高且可靠的电源解决方案。根据系统具体需求,在 PCB 布局、滤波与热管理上做适当优化,即可发挥模块最佳性能。

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.
