Critical Conduction GreenLine SMPS Controller

The MC33364 series are variable frequency SMPS controllers that operate in the critical conduction mode. They are optimized for high density power supplies requiring minimum board area, reduced component count, and low power dissipation. Integration of the high voltage startup saves approximately 0.7 W of power compared to the value of the resistor bootstrapped circuits.

Features

• Lossless Off−Line Startup

• Leading Edge Blanking for Noise Immunity

• Watchdog Timer to Initiate Switching

• Operating Temperature Range −25° to +125°C

• Shutdown Capability

• Over Temperature Protection

• Optional/Adjustable Frequency Clamp to Limit EMI

• Pb−Free Packages are Available

MC33364属于集成电路（IC） > AC DC 转换器，离线开关。安森美半导体公司制造生产的MC33364AC 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。
