ICE2QR4780Z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 with 800V avalanche rugged CoolMOS™, startup cell and QR current mode flyback PWM controller in DIP-7 package.  Capable for 19W SMPS design. The quasi QR CoolSET™ series continues to deliver design agility and miniaturization. Upon the successful F3 CoolSET™, this new series offer the possibility of higher efficiency and better EMI performance. The digital frequency reduction feature score a very stable operation with decreasing load change, and the fold-back correction keep the maximum power limits within tolerance desired by SMPS designers. The active burst mode operation during low power consumption, remains market leaders in providing best-in-class power consumption during standby.

简介

ICE2QR4780Z属于集成电路（IC）的ACDC转换器离线开关。由制造生产的ICE2QR4780ZAC 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。
