摘要

A simple and flexible control method for small size LCD backlighting is developed and verified. This proposed control method including a flexible and accurate current source stage for sub, main and keypad backlight with 1.5X mode charge pump technique. This paper provides useful application methods for sub, main, keypad and low cost & weak camera flash of mobile phone. The validity of this paper is confirmed by an experimental clamshell type mobile system.
