描述 Description

Integrated power management IC integrated with 650V avalanche rugged CoolMOS?, startup cell and fixed frequency current mode flyback PWM controller in DIP-8 package. Capable for 26W SMPS design. The additional features include an 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)

? 65kHz fixed switching frequency with frequency jitter (low EMI)

? adjustable blanking window, active burst mode (low standby power <100mW)

? enhanced integrated protection functions (auto-restart)

? accurate peak power limitation

? modulated gate drive

? auto-restart enable pin, etc.

優(yōu)勢:
? Extremely low standby power

? very accruate max power control

? low EMI noise, etc.

應(yīng)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, etc.

簡介

ICE3BR1765J屬于集成電路（IC）的ACDC轉(zhuǎn)換器離線開關(guān)。由制造生產(chǎn)的ICE3BR1765JAC DC 轉(zhuǎn)換器，離線開關(guān)該系列是元器件級控制產(chǎn)品，用于構(gòu)建將交流市電轉(zhuǎn)換為直流電（通常電壓大幅降低）的設(shè)備。集成和未集成系統(tǒng)主要開關(guān)元件的器件均包括在內(nèi)。由于高輸入輸出電壓比，以及此類系統(tǒng)中通常需要隔離，這些器件通常與外部變壓器配合使用。盡管通常使用定制變壓器來實現(xiàn)此用途，但也有許多專門用于此用途的庫存產(chǎn)品，請參見“開關(guān)轉(zhuǎn)換器，SMPS 變壓器”標(biāo)題。
