ICE3AR4780JZ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

Integrated power management IC integrated with 800V avalanche rugged CoolMOS™, startup cell and fixed frequency current mode flyback PWM controller in DIP-7 package. Capable for 17W SMPS design. The additional features include input brownout feature,  active burst mode operation to achieve extremly low standby power consumption, frequency jittering to obtain low EMI, adjustable blanking window to facilitate load jumps and high voltage startup cells that allows you to quickly power up your controller from the rectified line.

特性 Features

• Peak current control (current mode)

• 100kHz fixed switching frequency with frequency jitter (low EMI)

• adjustable blanking window

• enhanced active burst mode (low standby power <100mW)

• enhanced integrated protection functions (auto-restart)

• accurate peak power limitation

• modulated gate drive

• brownout

• auto-restart enable pin, etc.

优势:
• Extremely low standby power

• very accruate max power control

•  low EMI noise

• brownout, etc.

应用 Application

• Small power supply such as Blu-ray, DVD player, set-top box, game console, charger and auxiliary power of high power system such as LED TV, server or PC computer etc.

简介

ICE3AR4780JZ属于集成电路（IC）的ACDC转换器离线开关。由制造生产的ICE3AR4780JZAC 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。
