矽力杰SY5882ZFAC反激式电源控制器产品概述
SY5882ZFAC是矽力杰（Silergy）针对高压直流输入、中功率输出 场景优化的反激式电源控制器，核心面向工业辅助电源、家电变频模块等领域，具备宽输入范围、低待机功耗、高可靠性等特点，可满足严苛环境下的稳定供电需求。
一、核心定位与典型应用场景
该控制器聚焦42W级中功率供电，输入电压覆盖380V~450V（对应AC220V整流+PFC升压后的主流高压直流范围），输出稳定42V/1A，典型应用包括：
- 工业设备辅助电源：PLC、伺服驱动器的低功耗供电模块；
- 家电变频系统：变频空调、洗衣机的变频模块辅助电源；
- 通信基站辅助模块：基站内小型化低待机功耗电源。
二、关键电气参数解析
SY5882ZFAC的参数针对中功率反激场景做了针对性优化，核心指标如下：
- 输入输出：380V~450V DC输入，42V/1A（42W）输出，无需额外降压电路；
- 开关特性：55kHz固定频率，兼顾效率（避免高频损耗）与EMI设计难度；
- 待机功耗：34uA静态电流，待机总功耗降至毫瓦级，符合节能标准；
- 配置特点：外置开关管（可灵活选600V以上MOSFET）、无同步整流（简化电路、降低成本）。
三、拓扑结构与核心特性
采用反激式拓扑，结合自身控制特性，具备以下优势：
- 电气隔离：天然支持输入输出隔离，满足工业安全规范；
- 完善保护：内置逐周期过流（OCP）、输出过压（OVP）、输入欠压锁定（UVLO）、芯片过温（OTP）保护，避免器件损坏；
- 软启动：开机逐步提升输出电压，减少浪涌对负载与开关管的冲击；
- 电流模式控制：峰值电流模式响应快，输出稳定抗负载波动。
四、可靠性与环境适应性
- 宽温范围：-40℃~+150℃，适配工业高温舱体、家电密闭空间等严苛环境；
- 小型化封装：SOP-8通用封装，节省PCB空间，适配设备小型化需求；
- 抗干扰：内置EMI抑制，固定55kHz频率减少传导干扰，降低外部滤波成本。
五、应用设计注意事项
为确保系统稳定，设计需注意：
- 开关管选型：选600V以上MOSFET（如IRFP460A），导通电阻≤0.1Ω；
- 变压器设计：匹配55kHz，选EE19磁芯，计算匝比适配输入输出范围；
- 输出滤波：100μF电解电容+1μF陶瓷电容并联，控制纹波≤100mV；
- 保护调试：OCP阈值≈1.2A、OVP阈值≈46V，避免误保护。
SY5882ZFAC凭借灵活设计、高可靠性，成为中功率高压转低压反激电源的优选方案，可缩短开发周期、降低系统成本。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
