A0505S-2WR2 产品概述

一、概述

A0505S-2WR2 是 YLPTEC(易川) 推出的一款小体积、高效率的隔离式 DC/DC 模块。模块为定电压输入、隔离非稳压的正负双路输出,额定总功率 2W,专为板上电源系统中需要将一组与主电源隔离的 ±5V 电源的场合设计。体积小(19.5 × 7 × 10 mm、SIP 封装)、开关频率 100kHz、转换效率可达 86%,适合对体积和效率有要求但对输出精度要求不高的应用。

二、主要参数

  • 输入电压 Vin:4.75V ~ 5.25V(标称 5V,推荐电压稳定在 ±10% 内)
  • 输出:±5V,双通道
  • 输出功率:2W(总)
  • 输出电流(最大值):两个通道分别为 200mA 与 20mA(两路合计受总功率限制)
  • 最大容性负载:100µF(任一输出)
  • 隔离电压 Vrms:1.5kV
  • 转换效率:约 86%(典型)
  • 开关频率:100kHz
  • 纹波噪声:约 50mVp-p
  • 保护特性:具备短路保护与过热保护(一般为自动恢复型)
  • 工作温度:-40°C ~ +85°C
  • 尺寸(L×W×H):19.5 × 7 × 10 mm,SIP 封装

三、功能与特性

  • 小体积、轻量:SIP 封装适合集成到紧凑型电路板上。
  • 隔离输出:最高可达到 1.5kV 隔离,适用于需要电气隔离的场合(信号隔离、地环路抑制等)。
  • 双路输出:提供正负 ±5V 电压,便于驱动一些需要对称电源的设备或为不同部分提供独立供电。
  • 保护机制:内置短路和过热保护,提高系统可靠性(保护后通常为自动恢复)。
  • 效率较高:在小功率场合效率约 86%,有利于降低发热量。

四、典型应用场景

  • 纯数字电路:为逻辑隔离、接口隔离或小功率数字模块提供独立电源。
  • 继电器驱动电路:为驱动级提供隔离电压,防止干扰回流到主电源。
  • 数据交换与通信接口:用于对收发器、隔离型接口芯片供电,避免地环路。
  • 一般低频模拟电路:在对精度要求不高的模拟前端可作隔离供电(若需高精度请后级稳压)。

五、安装与使用建议

  • 输入电压稳定:模块为非稳压隔离型,建议输入电源在 5V ±10% 范围内,避免过大波动影响输出幅度。
  • 输出滤波与去耦:尽管模块可驱动高达 100µF 的容性负载,仍推荐在输出端并联低 ESR 的去耦电容以降低纹波和瞬态响应。
  • 散热与环境:在高环境温度或满载工作时应注意散热与布局,必要时在组件周围留出空气流通空间并考虑降额使用。
  • 布局注意:输入/输出端的走线尽量短且粗,旁路电容紧贴模块针脚,避免高频回路环路面积过大。
  • 保护行为:短路或过热保护多为自动恢复型,但频繁出现保护说明负载或散热存在问题,应查明原因并调整使用条件。

六、选型与注意事项

  • 若两个输出需相近或对称的大电流(如 ±200mA/±200mA),请确认本型号左右通道电流分配满足需求,否则应选择对称更高电流的型号。
  • 对输出电压稳定性、低噪声或低纹波有严格要求的仪器级模拟电路,建议在模块后加线性/低噪声稳压器或滤波电路。
  • 需要更高隔离电压、更多功率或更大容性负载能力时,可考虑同系列更高规格的产品。

总结:A0505S-2WR2 以其小尺寸、隔离特性和较高效率,适合板上为数字电路、接口隔离和小功力驱动电路提供稳定的 ±5V 隔离电源,是对体积与隔离有明确要求场合的实用选择。

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
