FAN604P数据手册集成电路（IC）的ACDC转换器离线开关规格书PDF

描述 Description

The FAN604P incorporates Quasi-Resonant (QR) control with proprietary Valley Switching with a limited frequency variation. QR switching provides high efficiency by reducing switching losses while Valley Switching with a limited frequency variation bounds the frequency band to overcome the inherent limitation of QR switching. FAN604P burst mode operation with extremely low operating current (300μA) and significantly reduces standby power consumption to meet the most stringent efficiency regulations such as Energy Star’s 5-Star Level and CoC Tier II specifications.
FAN604P includes several user configurable features aimed at optimizing efficiency, EMI and protections. FAN604P has a wide blanking frequency range that improves light load efficiency. It incorporates user configurable power limit reference (PLR), which allows controlling the maximum output power from primary-ide, thereby optimizing transformer design to improve the overall efficiency. It also includes several rich programmable protection features such as over-voltage protection (OVP), under-voltage protection (UVP) and externally triggered shutdown protection (SD).

简介

FAN604P属于集成电路（IC）的ACDC转换器离线开关。由制造生产的FAN604PAC 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。
