NCP1399AI开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS规格书PDF中文资料

NCP1399AI属于开发板套件编程器的评估板-DC/DC与AC/DC（离线）SMPS。由安森美半导体制造生产的NCP1399AI评估板 - DC/DC 与 AC/DC（离线）SMPS该系列产品提供了一种方便的方法，可对开关模式电源转换所用的器件（包括 DC-DC 和 AC-DC 型）进行性能或特性评估。“稳压器”（包含内部电源开关装置）和“控制器”（设计为控制外部电源开关）之类的器件均包括在内。

The NCP1399 is a high performance current mode controller for half

bridge resonant converters. This controller implements 600 V gate

drivers, simplifying layout and reducing external component count. The

built−in Brown−Out input function eases implementation of the

controller in all applications. In applications where a PFC front stage is

needed, the NCP1399 features a dedicated output to drive the PFC

controller. This feature together with dedicated skip mode technique

further improves light load efficiency of the whole application. The

NCP1399 provides a suite of protection features allowing safe operation

in any application. This includes: overload protection, over−current

protection to prevent hard switching cycles, brown−out detection, open

optocoupler detection, automatic dead−time adjust, overvoltage (OVP)

and overtemperature (OTP) protections.
