ICE3AR4780VJZ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

Off-Line SMPS Current Mode Controller with integrated 800V CoolMOS™ and Start up cell (input OVP & frequency jitter) in DIP-7
The ICE3AR4780VJZ is a modified version of ICE3ARxx80JZ (CoolSET™-F3R 800V) in DIP-7 package. It adds in the input OVP feature but removes the brownout feature and external protection enable feature. In summary, the ICE3AR4780VJZ is a device running at 100kHz, implemented with input OVP feature, installed with 800V MOSFET with startup cell and housed in DIP-7 package. It provides good voltage margin of MOSFET, lowest standby power, selectable burst level, reduced output ripple during burst mode, robust protection with input OVP feature, accurate maximum power control for both maximum power and burst power, low EMI with frequency jittering and soft gate drive, built-in and flexible protections, etc.

特性 Features

• 800V avalanche rugged CoolMOS™ with start up cell
• Active Burst Mode to reach the lowest Standby Power <100mW
• Selectable entry and exit burst mode level
• Adjustable blanking Window for high load jumps
• Frequency jitter and soft driving for low EMI
• Adjustable input OVP
• Auto Restart protection for over load, over temperature and over voltage
• Low Operating temperature down to -40°C
• Pb-free lead plating, halogen free mold compound, RoHS compliant

优势:

应用 Application

• Adapter/Charger
• Blu Ray/DVD player, Set-top Box, Digital Photo Frame
• Auxiliary power supply for Server, PC, Printer, TV, Home theater/Audio System, White Goods, etc.

简介

ICE3AR4780VJZ属于集成电路（IC）的ACDC转换器离线开关。由制造生产的ICE3AR4780VJZAC 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。
