초록
This paper presents a white-LED driver IC for a mobile application. It uses a high efficiency current mode boost converter method for a low voltage application. For a LED drive, it provides a PWM(Pulse Width Modulation) and analog dimming function. The device was designed and fabricated using 0.35um BCD process. The evaluated waveforms for an implemented IC show promising results.
