NCP1399中文资料电流模式谐振控制器（集成式高电压驱动器，高性能）数据手册ONSEMI规格书

描述 Description

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.

特性 Features

• High−Frequency Operation from 20 kHz up to 750 kHz
• Optimize for physical size or highest efficiency
• Current Mode Control Scheme
• Built-in safety protection, improved transient response
• Automatic Dead−time with Maximum Dead−time Clamp
• Improved efficiency

应用 Application

• High power AC/DC adapters for notebooks
• Offline battery chargers
• Industrial and medical power sources
• Computing power supplies
• Notebook Adapters
• LCD-TV / LED-TV

简介

NCP1399属于集成电路（IC）的ACDC转换器离线开关。由制造生产的NCP1399AC DC 转换器，离线开关该系列是元器件级控制产品，用于构建将交流市电转换为直流电（通常电压大幅降低）的设备。集成和未集成系统主要开关元件的器件均包括在内。由于高输入输出电压比，以及此类系统中通常需要隔离，这些器件通常与外部变压器配合使用。尽管通常使用定制变压器来实现此用途，但也有许多专门用于此用途的库存产品，请参见“开关转换器，SMPS 变压器”标题。
