Abstract

A fast-switching current-pulse driver for dimming controllers of LED backlight applications is proposed. The proposed current-pulse driver was fabricated in 0.25-μm 1P4M BCD high-voltage process. The measured rising time and falling time of the LED current are 120 ns and 12 ns, respectively, when the load is a 7-LED string.
