INN3670C-H606-TL 是 Power Integrations 面向中低功率隔离式 AC-DC 反激电源的高集成控制器/稳压器。器件集成高压开关晶体管(耐压 750V)、准谐振/多工作模式控制与完善的保护功能,典型开关频率 60kHz,采用小型 InSOP-24D 封装,适合对效率、尺寸和可靠性有严格要求的电源方案。
器件可在 CCM、QR 与 DCM 三种模式下工作,适配不同负载与转换器设计目标:QR 用于降低开关损耗与 EMI,CCM 提高轻负载效率与纹波控制,DCM 简化控制并改善欠载稳定性。副边反馈实现精确的 CV/CC 复合控制,适用于需要恒流限流与恒压稳压并重的应用,例如电池充电与 LED 驱动。
INN3670C-H606-TL 集成全面保护机制,提升系统可靠性:过热保护(OTP)、欠压保护(UVP)、过压保护(OVP)、过流保护(OCP)等。器件工作环境范围广,Ta -40℃ 至 +105℃,适应严苛工况。保护逻辑配合副边反馈能在异常工况下快速响应,防止器件与负载损坏。
InSOP-24D 小型表面贴装封装有利于缩小 PCB 面积和自动化装配。建议在 PCB 设计中配合大面积散热铜箔和短回流路径以保证热阻最小化;对于高功率或密集布局场合,应评估散热垫与通孔过孔以改善结到外壳的热通路。
适合手机/平板充电器、适配器、LED 驱动、电源模块、工业与家电小功率电源等隔离式电源方案。设计时重点关注:初级吸收回路与漏感控制、一次侧 EMI 滤波与差模抑制、次级反馈回路的环路带宽与补偿、以及 OVP/UVP 的阈值设定与容差。利用器件的多模式特性可在不同负载下优化效率与 EMI 表现。
总结:INN3670C-H606-TL 在高压耐受、丰富保护、灵活工作模式与紧凑封装间取得平衡,适合对尺寸、效率与可靠性有综合要求的隔离式反激电源设计。

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.
