SY58282NFAC是矽力杰(Silergy)推出的单通道降压型LED专用驱动器,采用小型化SO-8贴片封装,针对中功率LED照明场景设计,具备宽输入电压范围、内置多重保护及宽温适应性,可满足工业、消费及户外照明的可靠性需求。
该器件属于高集成度LED驱动解决方案,核心特点是“内置功率开关管+单通道降压”,无需外部MOSFET即可实现LED串驱动,减少BOM成本与PCB空间;拓扑结构为降压(Buck),适配输入电压高于LED串总电压的场景,覆盖中功率LED(100mA~500mA输出电流)应用。
该器件内置多重保护,提升系统可靠性,核心包括:
输出端短路(LED串断开/短路)时,自动进入打嗝模式:开关管间歇性关断(占空比<10%),限制输出电流至安全值(通常<50mA),避免自身及LED损坏;故障排除后自动恢复,无需手动复位。
内置结温检测,当结温超过150℃(与工作温度上限匹配)时,关断开关管;温度下降至120℃左右自动重启,防止热失控。
输出电流超过额定值1.2~1.5倍时,限制电流至阈值,避免LED过流老化或损坏(与SCP联动,短路时触发OCP并进入打嗝模式)。
采用SO-8贴片封装,尺寸为5.2mm×6.2mm,适合高密度PCB设计,兼容常规SMT生产流程,可直接替换同类小封装LED驱动器。
该器件适配以下常见场景:
SY58282NFAC凭借高集成度、宽适配性及可靠保护,成为中功率LED照明领域的高性价比选择,适用于对成本、体积及可靠性有要求的应用场景。

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.
