OB2362CMP 产品概述

一、产品概览

OB2362CMP(SOT-23-6)是昂宝(On-Bright)面向隔离型反激式AC-DC电源的PWM控制芯片,适用于中低功率开关电源和待机电源设计。芯片工作电压范围为12V~26V,典型开关频率60kHz~70kHz,最大占空比80%,通过副边反馈实现输出稳压与隔离控制,封装为紧凑的SOT-23-6,便于小型化电源方案。

二、主要特性

  • 拓扑:反激式(隔离型)PWM调制控制
  • 工作模式:固定频率PWM,开关频率60kHz~70kHz
  • 最大占空比:80%,提高能量传输能力,兼顾变压器重置余量
  • 保护功能:过热保护(OTP)、欠压保护(UVP)、过压保护(OVP)、过流保护(OCP)
  • 软启动:有效限制启动浪涌电流,改善启动过程稳定性
  • 反馈方式:副边(隔离)反馈,适合需安全隔离的AC-DC应用
  • 工作温度:-40℃~+85℃,适应工业级环境要求

三、典型应用场景

  • 小功率外置适配器与充电器(USB电源、手机充电器)
  • 待机电源与机顶盒、路由器等家电的辅助电源
  • 低功率LED驱动(需隔离场合)和工业控制小功率隔离供电模块

四、设计要点与建议

  • 变压器设计要保证在80%最大占空比下有足够的剩磁和重置裕量,避免磁芯饱和。
  • 副边取样反馈需保证辅助绕组电压在工作范围内稳定,外部整流与滤波元件应满足纹波与负载瞬态要求。
  • 保护电路(RCD泄放、缓冲吸收、TVS等)配合芯片内部OCP/OVP,可提升系统可靠性与抗雷击能力。
  • 开关频率60–70kHz在效率与体积之间取得平衡,注意布线与滤波以控制EMI。
  • SOT-23-6封装热阻相对较高,应优化PCB散热(铜铺、热孔)并考虑环境温升以确保在85℃条件下可靠工作。

五、封装与可靠性

SOT-23-6小封装利于高密度布置,但对散热与电气隔离提出更高要求。芯片集成多重保护,有利于简化外围电路、降低设计复杂度。器件通过工业温度级测试,适合长时间稳定运行的消费与工业产品。

六、优势总结

OB2362CMP以紧凑封装和全面的保护机制为特征,适合空间受限且需安全隔离的中低功率反激电源方案。内建软启动与多重保护,配合合理的磁性元件与吸收电路,可实现高可靠性、成本优化的AC-DC设计。

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
