This paper proposes a current-mode DC-DC boost converter for automotive LED headlamp driver. Recently, the trends of an evolution of the LEDs composed by huge pixel, instead of a unit of the LEDs. Therefore, the specifications of DC-DC converters would be much important to operate number of LEDs. In this paper, the current-mode boost converter is proposed to have much wider load current range than the conventional voltage-mode control method. Meanwhile, circuit implementations of building blocks for the proposed boost converter are also presented. The proposed converter has been fabricated through TSMC 0.18-μm 60 V BCD process. The converter operates at a 10 MHz high switching frequency.
