摘要
本PD控制器集成开关稳压器,内置同步反激式控制器,符合IEEE802.3at标准,提供25.5 W的高功率输出。支持宽电压输入及外部辅助电源输入,具有欠压、过压、过流和热保护功能,在大负载的情况下电源效率达到88%。实际PD模块验证表明,该电源模块在以太网供电应用领域,具有很突出的优势,拓宽了以太网电缆供电的应用范围。
The PD controller integrates the switching regulator and the synchronization {lyback controller, which is in accord with IEEES02.3at standard, and can provide 25.5 W high power output. The controller supports wide voltage input and the external auxiliary power input, has the protection functions such as under voltage,over voltage,over current and thermal protection functions. In the ease of large load power, the efficiency can reach 88%. The actual PD module verification shows that the power supply module has prominent advantage in Ethernet power supply applications,broadens the application range of the Ethernet cable power supply.
