控制可变电压电源使用DS1809 （按键控制）

摘要：半导体话题：许多线性和交换式电源供应器和稳压器使用一个电阻网络调节的反馈来调整输出电压。这通常是由不同的单个电阻值，或使用机械电位。本文讨论了用按钮控制， DS1809的电压调节器的控制，这给了“人机界面”数字电位器控制电压调节器。这可以用来参考其他数字控制电源使用其他可以由微处理器控制的数字电位器供应。这本身应用系统电压水平调整到最佳水平，在制造过程中，提供最佳的电源电压和工作电压的电路中的设备之间的错误保证金。

APPLICATION NOTE 183
Controlling a Variable Voltage Power Supply Using the DS1809 (Pushbutton
Control)

Abstract: Semiconductor topic: Many linear and switched-mode power supplies and voltage regulators use a resistor network
as feedback into the regulator to adjust the voltage output. This is typically done either by varying the values of the individual
resistors or using a mechanical potentiometer. This article discusses controlling a voltage regulator using a digital
potentiometer with pushbutton controls, the DS1809, which giv
