ICE5AR4780BZSXKLA1 产品概述
一、器件简介
ICE5AR4780BZSXKLA1 为 Infineon（英飞凌）推出的一款隔离型 AC‑DC 控制器与稳压器，采用反激拓扑并集成内部开关，适用于 15W 级小功率电源。器件集成了启动电路与稳压供电，工作电压范围宽（Vcc/Vdd 10V ~ 25.5V），启动电压约 16V，开关频率典型值 100kHz，占空比最高可达 75%，能满足多种通用消费类与工业类电源设计需求。
二、主要参数与功能要点
- 隔离输出：支持初次侧与次级完全隔离的拓扑实现。
- 内部开关：集成功率开关，额定击穿电压 800V，适合直接与整流高压相连。
- 拓扑：反激（Flyback）结构，适合中低功率多输出或单输出隔离电源。
- 功率等级：典型应用功率约 15W。
- 开关频率：100kHz，平衡磁性元件体积与效率。
- 占空比：最大 75%，提高转换比与低线压启动能力。
- 供电要求：Vcc/Vdd 10V~25.5V；启动电压 16V（内置启动电路）。
三、保护与控制特性
器件内建多种保护机制，提升系统可靠性：
- 限流保护：防止短路或过载时过大电流损坏器件。
- 开路与过载保护：适应负载突变与次级故障情形。
- 过温保护：当结温超出工作温度范围自动限制或关断。
- 过压保护：抑制输出侧或器件内部异常电压。
此外，器件支持 EN 控制、软启动和同步功能，方便系统级的控制与功率管理。
四、封装与环境特性
- 封装形式：PG‑DIP‑7（8‑DIP 封装风格、7 引脚，通孔安装），便于传统 PCB 与散热设计。
- 工作温度：结温（TJ）范围 -40°C ~ 125°C，适合较为苛刻的环境。
五、典型应用场景
适用于手机充电器、适配器、小型工业电源、机顶盒、电视待机电源及家电控制板等需要隔离、15W 级别稳压的场合。反激拓扑可支持多路输出设计，且封装利于快速打样与小批量生产。
六、设计建议与注意事项
- 初级磁性元件与屏蔽、漏感控制需根据 100kHz 工作频率优化，以兼顾效率与 EMI。
- 启动与供电电容、滤波器设计需保证 Vcc 在 10V~25.5V 范围内稳定；启动电路应能在约 16V 条件下可靠触发。
- 布局上注意初次侧与次级之间保持隔离距离，地线回流路径短且分离以降低 EMI 干扰。
- 散热方面，尽管为通孔封装，仍需评估 PCB 铜箔和通孔散热能力以保证在高负载下结温不超限。
七、总结
ICE5AR4780BZSXKLA1 以其高压击穿能力、内置开关和全面保护特性，为 15W 级隔离型 AC‑DC 设计提供了可靠且易于实现的解决方案。适合需要稳健保护与通孔封装便捷组装的应用场景，在合理的磁性元件与 PCB 布局配合下，可实现高效、稳定的电源设计。

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.
