Realization of an integrated LED driver with boost converter with the use of standard CMOS technology is presented in this paper. By considering Lithium-Ion battery in driving LED strings, an overall maximum efficiency of 85% and current error accuracy of 0.0046% is achieved. The boost converter operates in PWM voltage mode at 600 kHz with stable output voltage as a voltage source to LED driver. Moreover,...
This paper presents the design of a novel wide output current range dual-mode dc to dc step-down (Buck) switching regulator/converter. The converter can adaptively switch between pulsewidth modulation (PWM) and pulse-frequency modulation (PFM) both with very high conversion efficiency. Under light load condition the converter enters PFM mode. The function of closing internal idle circuits is implemented...
