SY58201FAC是矽力杰(Silergy)推出的一款专为LED照明设计的AC-DC开关电源驱动器,集成功率因数矫正(PFC)功能,采用反激拓扑结构,以高集成度、宽适应性和能效优势,适配各类LED照明场景的电源需求。
作为AC-DC转换器件,SY58201FAC采用反激式拓扑结构——该拓扑适合中小功率(LED照明多为10W-50W级别)应用,具备隔离/非隔离设计灵活性,且通过120kHz的开关频率优化,可缩小外围电感、变压器等器件体积,提升电源模块的功率密度,适配照明产品的紧凑结构需求。
支持90VAC~264VAC的全球通用市电输入范围,无需额外切换电路,即可兼容中国(220VAC)、北美(110VAC)等不同地区的电网电压,降低跨区域产品的设计成本。
集成功率因数矫正(PFC)功能,可将功率因数提升至符合能源之星(Energy Star)、欧盟ERP等能效标准要求,减少电网谐波干扰,提高电能利用率,降低LED照明的运营成本,同时满足照明产品的能效认证需求。
采用1通道输出设计,针对性适配单路LED负载(如单串LED灯珠),简化电路拓扑;同时内置功率开关管,无需外置MOSFET,减少BOM(物料清单)成本,缩小PCB面积,降低外部连接点故障风险,提升整体可靠性。
SY58201FAC采用SO-8封装(8脚表面贴装),体积小巧,适合球泡灯、筒灯、面板灯等紧凑照明产品的内部空间布局;集成PFC控制、开关管、反馈调节等核心功能,外围仅需少量电容、电感、电阻即可实现完整电源方案,降低设计难度与生产复杂度。
工作温度范围覆盖**-65℃~+150℃**,远超常规照明驱动器的温度阈值,可适配户外照明(如庭院灯、小功率路灯)、工业照明(如厂房灯、冷藏库照明)等极端温度场景,减少因温度变化导致的器件老化或故障,保障长期稳定运行。
SY58201FAC专为LED照明领域打造,典型应用包括:
由矽力杰(Silergy)研发生产——该品牌专注电源管理芯片10余年,在LED驱动领域拥有成熟技术积累,SY58201FAC经过严格的可靠性测试(如高低温循环、老化测试),符合RoHS等环保标准,可保障照明产品的长期稳定运行。
总结:SY58201FAC以高集成度、宽适应性、能效优势,成为LED照明领域中小功率AC-DC驱动的优选方案,适配各类紧凑、宽温场景的照明产品需求。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
