Abstract :
A high-voltage LED driver using Silicon-on-Insulator (SOI) technology is presented in this paper. The presented LED driver has a wide input range from 40V to 625V, and could be used in tens to a hundred series LED applications. This driver works in peak current control mode, which provides two dimming functions: linear dimming and PWM dimming. The output current requirement could be fulfilled by adjusting the external current sensing resistor. The prototype chip is designed and implemented using XFAB 1-μm SOI Process.
