QA151 产品概述
一、核心特性
QA151 为 YLPTEC(易川) 推出的双路隔离式 DC-DC 模块，采用 SIP-5 封装，提供一路 -8V 和一路 +15V 输出。模块输入电压范围为 14.25V ~ 15.75V（标称 15V），转换效率高达 87%，最大单路输出电流 120mA，能够在紧凑尺寸（19.5 × 9.8 × 12.5 mm）下实现稳定双路供电，并具备 3kVrms 的输入-输出隔离能力，适合对隔离与抗干扰有一定要求的工业和仪表场合。
二、典型电气参数
- 输入电压（Vin）：14.25V ~ 15.75V（标称 15V）
- 输出电压（Vout）：-8V、+15V（双路）
- 最大输出电流：120mA（单路）
- 转换效率：87%（满载条件下典型值）
- 最大容性负载：1000µF（需注意电容 ESR 对启动与稳定的影响）
- 纹波噪声：200mVp-p（典型值）
- 开关频率：200kHz
- 静态电流：35mA（空载功耗）
- 隔离电压：3kVrms
- 工作温度：-40℃ ~ +105℃
三、保护与可靠性
模块内置短路保护并支持自动故障恢复（auto-recovery），在输出短路或过载时进入保护状态，故障消除后自动恢复正常工作，便于无人值守系统使用。额定工作温度范围宽广，最高可达 +105℃，适应苛刻工业环境；3kVrms 的隔离性能也有助于提高系统安全性与抗共模干扰能力。
四、封装与机械尺寸
使用 SIP-5 直插封装，尺寸紧凑（长 19.5 mm、宽 9.8 mm、高 12.5 mm），便于通过插针安装在标准 PCB 上进行可靠的机械固定与电气连接。SIP 封装适合需要隔离通道但空间受限的应用场合。
五、应用场景
适用于需要双极供电或隔离偏置的系统，例如精密模拟前端（运放偏置）、工业控制器、数据采集模块、通信设备的局部偏置电源、传感器驱动与隔离测量等。特别适合以 15V 为主电源的系统中，需同时生成 -8V 与 +15V 的场合。
六、选型与使用建议
- 输入供电应稳定在 15V 附近，避免长时间运行在输入边界，以减少热损耗并保证输出稳定。
- 对于大容性负载（接近 1000µF），应关注启动电流与输出稳定性，建议在输出端并联小容量低 ESR 的去耦电容（如 0.1µF 陶瓷）与若干 µF 电解/铝聚合物电容，以降低纹波并改善瞬态响应。
- 由于纹波约 200mVp-p，敏感模拟电路建议在模块输出端增加滤波与局部稳压/基准电路。
- 布局时尽量缩短输入电源与模块之间的走线，输入端并联高频旁路电容，输出端保持良好接地回路，保持输入-输出间距以满足隔离要求。必要时在输入侧增加保险丝或 TVS 以增强系统保护。
QA151 以其小尺寸、高效率与双路隔离输出的组合，适合工程项目中对空间、隔离与可靠性有要求的电源设计。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
