ICE3B2065J集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

ICE3B2065J属于集成电路（IC）的ACDC转换器离线开关。由英飞凌科技股份公司制造生产的ICE3B2065JAC 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。

描述 Description

The CoolSET®-F3(Jitter version) meets the requirements

for Off-Line Battery Adapters and low cost SMPS for the

lower power range. By use of a BiCMOS technology a wide

VCC range up to 26V is provided. This covers the changes

in the auxiliary supply voltage if a CV/CC regulation is

implemented on the secondary side. Furthermore an Active

Burst Mode is integrated to fullfill the lowest Standby Power

Requirements <100mW at no load and Vin = 270VAC. As

during Active Burst Mode the controller is always active

there is an immediate response on load jumps possible

without any black out in the SMPS. In Active Burst Mode

the ripple of the output voltage can be reduced <1.

Furthermore Auto Restart Mode is entered in case of

Overtemperature, VCC Overvoltage, Output Open loop or

Overload and VCC Undervoltage. By means of the internal

precise peak current limitation, the dimension of the

transformer and the secondary diode can be lowered which

leads to more cost efficiency.
