POWER REGULATION OF LED BY MEANS OF AN AVERAGE VALUE THE LED CURRENT AND BIDIRECTIONAL COUNTER
摘要
<p>A circuit for the power regulation of an LED comprises a converter having a switch. The LED is interconnected in an output circuit, wherein a control unit controls the magnetization of an inductor, in that it actively clocks the switch. A measured actual value representative of the average value of the LED current is returned to the control unit and compared to a reference value.</p>
