A High-Frequency Digitally Controlled LED Driver for Automotive Applications With Fast Dimming Capabilities

Abstract

This paper presents a high-frequency, digitally controlled high-brightness LED driver for automotive applications with fast dimming capabilities. The power converter is based on the magnetically coupled Ćuk topology and employs a single, off-the-shelf SMT mutual inductor. The proposed digital control technique exploits the inherent stabilizing effect of… (More)
