This application report shows how to operate the TPS61041 in a constant current LED drive configuration from input voltages less than 1.8 V. Although most applications using this device connect the VIN pin to the boost inductor L1 as shown in Figure 1 this is not required. Separating the power stage from the control IC allows the use of input voltages that are both above or below the operating
