说明

MAX5969A评估板(EV kit)是完全安装并经过测试的表贴电路板,安装了MAX5969A IEEE 802.3af/at兼容的网络用电设备(PD)接口控制器和MAX5974A电感反馈、频谱扩展、电流模式PWM控制器。评估板设计提供高性能、结构紧凑的高性价比3级(可升级到4级) PD解决方案,用于以太网供电(PoE)系统。

评估板能够演示MAX5969A的所有功能,例如:PD侦测信号、PD分级信号、浪涌电流控制和输入欠压锁定(UVLO)。评估板还带有一路12W、300kHz开关频率、同步整流、反激式DC-DC隔离转换器,采用MAX5974A电感反馈、电流模式PWM控制器构成。评估板电路配置为+12V输出电压,采用原边稳压,可提供高达1A的负载电流。表贴变压器为输出提供高达+1500V的电气隔离。

评估板由符合IEEE® 802.3af/at标准的供电设备(PSE)供电。PSE通过非屏蔽双绞线以太网电缆提供所需的-36V至-57V直流电源,连接到评估板的RJ45磁性插孔。评估板安装了一个1 x 1Gb以太网RJ45磁性插孔和两组全桥二极管,分别用于端点或中跨以太网系统的直流电源。

评估板电路也可以由+36V至+57V电源适配器供电,将其作用在WAD_IN和WAD_GND PCB焊盘。当检测到电源适配器时,系统将优先选择适配器(而非PSE)给评估板供电。

注意:评估板设计工作在高压环境,评估板及其连接设备存在危险的高压。用户在给评估板上电或连接电源时必须遵循高压电气设备的安全操作步骤。

出现严重故障或失效条件下,评估板可能消耗大量功率,导致元器件发生机械破裂或高速溅出。操作评估板时须务必谨慎,避免潜在的人身伤害。
