TOP200集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

TOP200属于集成电路（IC）的ACDC转换器离线开关。由荷兰帕沃英蒂格盛有限公司制造生产的TOP200AC 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。

Low Cost Replacement for Discrete Switchers

• 20 to 50 fewer components - cuts cost, increases reliability

• Source-connected tab and Controlled MOSFET turn-on

reduce EMI and EMI filter costs

• Allows for a 50 smaller and lighter solution

• Cost competitive with linears above 5 W

Up to 90 Efficiency in Flyback Topology

• Built-in start-up and current limit reduce DC losses

• Low capacitance 700 V MOSFET cuts AC losses

• CMOS controller/gate driver consumes only 6 mW

• 70 maximum duty cycle minimizes conduction losses

Simplifies Design - Reduces Time to Market

• Supported by many reference design boards

• Integrated PWM Controller and 700 V MOSFET in a

industry standard three pin TO-220 package

• Only one external capacitor needed for compensation,

bypass and start-up/auto-restart functions

System Level Fault Protection Features

• Auto-restart and cycle by cycle current limiting functions

handle both primary and secondary faults

• On-chip latching thermal shutdown protects the entire

system against overload

Highly Versatile

• Implements Buck, Boost, Flyback or Forward topology

• Easily interfaces with both opto and primary feedback

• Supports continuous or discontinuous mode of operation
