ICE5GSAG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

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

• 125kHz 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

优势:
• 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

应用 Application

• Offline aux SMPS for server, PC power, aircon, refrigerator and audio
• Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE

简介

ICE5GSAG属于集成电路（IC）的ACDC转换器离线开关。由制造生产的ICE5GSAGAC 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。
