A0512S-2WR2 产品概述

一、产品简介

A0512S-2WR2 是 YLPTEC(易川)推出的一款小体积、高效率的板上隔离 DC/DC 模块,属于定电压输入、非稳压的正负双路输出微功率电源。该模块专为在电路板上需要与输入电源隔离的场合设计,体积紧凑,适合空间受限且对隔离有要求的系统。典型输入为 5V(4.75V~5.25V),可提供 ±12V 的隔离输出,输出总功率 1W,转换效率高达 86%。

二、主要技术参数

  • 输入电压 Vin:4.75V ~ 5.25V(定电压输入,建议 Vin 波动在 ±10% 以内)
  • 输出通道数:2(正负双路)
  • 输出电压 Vout:±12V(非稳压)
  • 输出功率:1W(总)
  • 输出电流(最大):84mA;8mA(按厂方标注的两路最大输出值)
  • 最大容性负载:100µF
  • 隔离电压 Vrms:1.5kV(1500Vrms)
  • 转换效率:86%(典型)
  • 开关频率:100kHz
  • 纹波噪声:100mVp-p(典型)
  • 保护功能:短路保护、过热保护
  • 工作温度:-40℃ ~ +85℃
  • 封装/外形:SIP,尺寸 19.5mm × 7mm × 10mm

三、功能特点

  • 小型化:SIP 封装,适合 PCB 密集布局。
  • 隔离性能:输入与输出之间隔离电压高达 1500Vrms,适用于需要信号/电源隔离的场合。
  • 双路输出:提供正负双轨 ±12V,满足对称供电或负电压需求。
  • 保护机制:内置短路保护与过热保护,提高系统可靠性。
  • 容性驱动能力:支持最高 100µF 的输出容性负载,利于滤波和稳定输出。

四、典型应用

  • 纯数字电路的隔离供电(如接口隔离、逻辑电平转换)
  • 一般低频模拟电路(对输出精度要求不高的放大、传感器前端)
  • 继电器驱动、微小功率执行器驱动电路
  • 数据交换、电平隔离模块、通信接口隔离等板上电源场合

五、使用建议与注意事项

  • 输入电源应相对稳定,建议在 5V ±10% 范围内使用,以保证输出在预期值附近。
  • 由于为非稳压输出,负载变化会影响输出电压,重要测量或精密模拟场合请加稳压或后级调整电路。
  • 输出电流标注为 84mA 与 8mA,请根据实际需求合理分配负载,避免超出单路能力导致电压漂移或保护动作。
  • 输出端建议并联合适的去耦电容(不超过 100µF),并将电容尽量靠近模块引脚布置,以降低纹波和干扰。
  • 布线时输入侧与输出侧应分区布置,保持隔离间距;散热不足时注意通风或留热路径,避免过热保护触发。
  • 在高噪声或敏感模拟环境中,可在模块输出加 RC/LC 滤波以降低纹波对后级电路的影响。

六、封装与选型指引

  • SIP 小体积封装(19.5 × 7 × 10 mm),易于插装或焊接在 PCB 上,适合批量化装配。
  • 选型时关注两路输出的电流分布与实际负载需求,若需要更高稳定性或更大功率,应考虑线性/开关稳压器或更高功率的隔离模块。

七、总结

A0512S-2WR2 以小体积、高隔离、良好效率与基本保护功能为特点,适合板上需要隔离 ±12V 微功率电源的应用场合。对于输入稳定、对输出稳压要求不高的数字隔离、继电器驱动与数据交换电路,该模块提供了经济可靠的解决方案。选用时需注意各路最大电流及输出非稳压特性,合理布线与去耦可取得最佳性能。

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.
