摘要： A current source and an associated method for supplying current to a load such as an arrangement of LEDs. The intensity of the supplied current varies as a function of the temperature of the load. The intensity of the current is temperature-dependent and limited to a predefined maximum. The temperature dependence is achieved by the component parts that are used without the help of special temperature sensors. The current source is supplied with a reference voltage derived from an integrated circuit. The reference voltage is tapped from a port of the IC and therefore it is switchable. The reference voltage is used to produce a control current, which is fed through a driver stage to produce the current of the current source. Elements in the current source limit the current's intensity and change it as a function of temperature.
摘要翻译：用于向诸如LED的布置的负载提供电流的电流源和相关联的方法。供电电流的强度根据负载的温度而变化。电流的强度取决于温度，并限制在预定的最大值。温度依赖性是通过在没有特殊温度传感器的帮助下使用的部件实现的。电流源提供有源自集成电路的参考电压。参考电压从IC的端口抽头，因此可以切换。参考电压用于产生控制电流，其通过驱动级馈入以产生电流源的电流。电流源中的元素限制了电流的强度，并将其作为温度的函数而改变。
