NCP1398中文资料控制器，高性能，谐振模式，带集成高电压驱动器数据手册ONSEMI规格书

描述 Description

The NCP1398 is a high performance controller for half bridge LLC resonant converters. The integrated high voltage gate driver simplifies layout and reduces external component count. A unique architecture, which includes a 750 kHz Voltage Controlled Oscillator whose control mode permits flexibility when an ORing function is required allows the NCP1398 to deliver everything needed to build a reliable and rugged resonant mode power supply. The NCP1398 provides a suite of protection features with configurable settings to allow optimization in any application. This includes: auto-recovery and latch-off over-current protection, brown-out detection, open optocoupler detection, adjustable soft-start and dead-time.

简介

NCP1398属于集成电路（IC）的ACDC转换器离线开关。由制造生产的NCP1398AC 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。
