MC33363B集成电路（IC）的ACDC转换器离线开关规格书PDF中文资料

MC33363B属于集成电路（IC）的ACDC转换器离线开关。由安森美半导体公司制造生产的MC33363BAC 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。

The MC33363B is a monolithic high voltage switching regulator that is specifically designed to operate from a rectified 240 Vac line source. This integrated circuit features an on--chip 700 V/1.0 A SENSEFET power switch, 500 V active off--line startup FET, duty cycle controlled oscillator, current limiting comparator with a programmable threshold and leading edge blanking, latching pulse width modulator for double pulse suppression, high gain error amplifier, and a trimmed internal bandgap reference. Protective features include cycle--by--cycle current limiting, input undervoltage lockout with hysteresis, overvoltage protection, and thermal shutdown. This device is available in a 16--lead dual--in--line and wide body surface mount packages.
