描述 Description

Infineon's latest 5th generation fixed frequency flyback PWM controller offers high performance and a?comprehensive suite of protection to increase system robustness.

特性 Features

? 100kHz maximum switching frequency
? Brown in protection, fast and robust start-up operation with cascode configuration
? 3 level selectable entry/exit active burst mode profile (optional)
? Built-in digital soft-start
? Cycle by cycle peak current limitation
? Support both DCM and CCM operation with slope compensation
? Integrated error amplifier to support direct feedback typical with non-isolated flyback topology
? Digital frequency reduction with decreasing load for higher efficiency
? Adjustable line input over voltage protection (optional)
? VCC and CS pin short to ground protection
? OLP, output short, OTP with hysteresis and VCC over/under voltage protection
? Auto-restart for all protection features

優(yōu)勢:
? Reduce BOM count and cost with integrated line input over voltage protection and error amplifier
? Increase mid and light load efficiency with digital frequency reduction
? High power delivery with slope compensation for CCM operation

應(yīng)用 Application

? Offline aux SMPS for server, PC power and major home appliances (e.g. air conditioning, washing machines and refrigerator)
? Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE

簡介

ICE5ASAG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ICE5ASAGAC 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。
