任何电子设备都离不开功率器件。集成电路的问世,促进了整机的小型化、提高了生产效率和可靠性,同时对功率器件的集成化提出了要求。目前的集成工艺技术,还不能生产高耐压、大电流的功率集成电路。国际上自从七十年代开始发展单片功率达林顿电路。它既具有功率晶体管的高耐压、较好的大电流特性,又具有较高的电流增益。因此,它的出现使功率器件向大功率集成迈出了可喜的一步,目前已发展到几千个品种。
Any electronic device can not do without power devices. The advent of integrated circuits, to promote the miniaturization of the machine, improve production efficiency and reliability, while the power device integration requirements. The current integrated technology, but also can not produce high voltage, high current power integrated circuits. Internationally, monolithic power Darlington circuits have been developed since the 1970s. It has the power transistor high voltage, good high current characteristics, but also has a high current gain. As a result, its emergence has made a welcome step towards high-power integration of power devices and has now grown to several thousand.
