应用MAX743获取可调电源的新方法

A new method of adjustable power generation based on MAX743

针对MAX743基本电源电路只能输出±15 V和±12 V这两个电压等级、无法满足电路设计实际需要的问题,提出了两种改进办法:一是采用不同电阻分压网络,二是从反馈电路着手调整输出电压.实验表明,改进后的方法能够获得输出电压可调的电源.

To solve the problem that only two kinds of voltages can be generated by MAX743 in its basis application, two advanced methods are put forward to generate diversified voltages：one is to adopt different circuit resistance dividing network, another is to adjust output voltage by feedback circuit. The experimen- tal results show that the power with adjustable output voltage can be generated by the advanced methods.
