Abstract :
This paper presents the optimal light-emitting-diode (LED) array combination for the peak current mode discontinuous-conduction-mode (DCM) boost driver, based on the efficiency consideration. The design guideline to specify the conduction mode for the operation of the employed boost driver corresponding to the combinations of an N×M LED array is proposed. The prototype circuit is built to compare the efficiencies with different combinations of an 120-pcs LED array.
