OB5282CPA 是昂宝(On-Bright)推出的一款用于隔离式反激(flyback)拓扑的 AC-DC 控制器。IC 采用 SOP-8(150 mil)封装,专为中低功率开关电源设计,支持副边反馈(通过光耦/参考整定输出),工作环境温度范围为 -40℃ 至 +85℃,适合通用适配器、电源模块与备用电源等场合。
OB5282CPA 集成多重保护,常见行为包括:
SOP-8_150mil 适合自动贴装与波峰/回流焊工艺。长期可靠性与热循环性能受 PCB 布局、散热设计及工作环境影响,建议在 85℃ 环境与最大功率下进行系统级验证。
OB5282CPA 以其完备的保护功能、适中的开关频率和较高的最大占空比,适合构建小型隔离式反激电源。设计时重点关注变压器复位、反馈环路稳定与热管理,可实现稳定、高效的 AC-DC 电源解决方案。有关详细引脚定义、典型电路与电气参数,请参照昂宝官方数据手册。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
