概览

NCP1083 属于安森美半导体的大功率 HIPO™ 以太网供电器件 (PoE-PD) 系列产品，是一个适用于高要求中高功率以太网应用的、耐用、灵活且高度集成的方案。它在一个器件中结合了完全符合 IEEE D3.0 规范和即将推出的 IEEE 802.3at (D3.0) 规范草案的增强型 PoE-PD 接口和灵活的可配置 DC-DC 转换器控制器。NCP1083 的卓越功能还支持从交流电源适配器和电池供电等辅助电源供电，使得应用能够从非 PoE 网络平滑转换为 PoE 网络，因此无需辅助开关电源。安森美半导体独特的制造工艺和设计增强使得 NCP1083 能够提供最高 25.5 W 且符合 IEEE 802.3at (D3.0) 草案标准的电源，以及用于专属大功率 PoE 应用的最高 40 W 的电源。NCP1083 实现了 IEEE 802.3at (D3.0) 草案标准符合，实施了两事件物理层类别。其他专属分类过程支持市场上的大功率电源设备 (PSE)。这些独特的大功率功能将将具有 PoE 功能系统的明显成本优势运用于新兴市场上的多种产品，如工业以太网设备、PTZ 和 Dome IP 摄像头、RFID 读取器、MIMO WLAN 接入点、高端 VoIP 电话、笔记本电脑等。该集成式电流模式 DC-DC 控制器可实现隔离式和非隔离反激、正向和降压转换器拓扑结构。它具有一个灵活、耐用和高能效设计所需的所有功能，包括可编程开关频率、高达 80% 的占空比、斜率补偿和软启动。NCP1083 使用耐用的高电压工艺制造，将坚固的垂直 N 沟道 DMOS 与低损耗电流感应技术进行集成，适用于要求最高的环境。
