This application note describes how to extend the battery life of a circuit that uses Texas Instrument's TPS61040 low power dc-dc boost converter for driving white light LEDs. Power loss in the current sense resistor is discussed and a method for reducing this loss is presented. Design equations are given for calculating the proper resistor values for a white light LED driver that includes prov
