... LED1 <Fig. 2 LED current test> possible to calculate the LED current by measuring of ICC current. As the ADT7110 is basically buck converter, its ICC current is the function of VIN, VOUT, LED branch current and quiescent current. Therefore it is not easy to calculate accurate LED current by measurement of ICC current. ...
