A white LED backlight driving IC with 3-bit dimming controller

This paper presents a white LED backlight driving chip with 3-bit dimming controller and duty-variable power MOS which can be modified with the voltage-mode pulse width modulation (PWM). In the proposed chip, a 3-bit digital-to-analog converter (DAC) and a ramp generator are used to provide eight pu...
