A1212S-2WR3 产品概述

一、产品简介

A1212S-2WR3 是易川(YLPTEC)推出的一款高效率双通道隔离型 DC-DC 转换器,面向 12V 车载及工业供电环境。模块采用 SIP 封装,体积小巧(19.5 × 7 × 10 mm),输入电压范围 10.8V~13.2V(适配典型 12V 系统),转换效率高达 90%,通过校验,适合对体积、隔离和低静态功耗有要求的嵌入式电源应用。

二、主要电气参数

  • 通道数:2(双输出)
  • 输入电压 Vin:10.8V ~ 13.2V
  • 输出电压 Vout:±12V(对地隔离输出)
  • 输出功率:总功率 2W
  • 输出电流(最大):±84mA(主通道);±5mA(辅助或次级通道)
  • 转换效率:典型 90%
  • 开关频率:100kHz
  • 空载输入电流:2mA
  • 纹波噪声:30 mVp-p(典型)
  • 最大容性负载:330 μF
  • 隔离电压 Vrms:1.5 kV

三、功能与保护

模块具备短路保护功能,可在输出短路或过载时提供保护机制以避免器件损坏。高隔离电压(1.5 kV)保证输入与输出之间的安全隔离,适合要求信号隔离或地回路隔离的场合。低空载电流特性有利于待机功耗控制。

四、应用场景

  • 汽车与车载电子(12V 总线):仪表、传感器供电隔离
  • 工业控制与自动化:隔离型信号调理、数据采集前端
  • 通信设备与嵌入式系统:为小功率模拟或数字电路提供正负对称电源
  • 需要高隔离与低噪声的测量类电路

五、封装与环境适应性

SIP 封装便于串排安装与点对点焊接,尺寸 19.5×7×10 mm,占板面积小。工作温度范围宽 (-40℃~+85℃),适应室外与工业级环境要求。

六、设计与使用建议

  • 输入端建议加 10 μF~47 μF 低 ESR 电解/固态电容做去耦,降低输入纹波并提高稳定性。
  • 输出端若驱动较大容性负载,应注意不超过 330 μF 的最大容性负载限制,以免影响稳定性与瞬态响应。
  • 布局时保持输入/输出回路短且宽,隔离区两侧留足爬电距离,确保隔离性能与 EMC 表现。
  • 在高温或长时间满载工作场合,应做适当热设计与功率热耗散评估,必要时降额使用以延长寿命。

简洁可靠的小功率隔离模块,适合需要正负对称小电流输出、隔离保护和低功耗待机的应用场合。

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
