串行数模转换器了TLC5615及在开关电源中应用

The Digital-to-analog Converter TLC615 with Serial Interface and Its Application in The Switching Mode Power Supply

本文介绍了串行数模转换器TLC5615的特点和功能，说明了在IGBT开关电源中与AT89C51单片机的接口电路，最后给出了程序设计。TLC615与单片机只有三线接口，因此硬件电路的设计大为简化。

This paper introduces the features and functions of the digital-to-analog converter TLC5615with serial interface, the interface circuit with AT89C51 single-chip microcomputer in The Switching Mode Power Supply of IGBT, and the design of program. TLC5615 requires only 3-wire interface with single-chip microcomputer, so the hardware circuit becomes simple.
