Aiming at compact-smartphone and portable-media-player applications, the NCP5890 lighting-management device integrates LCD backlighting, light controls, and ambient light sensing. Providing a 30V output capability, the device drives LEDs to achieve homogeneous backlighting over an LCD screen. The device also controls three sets of white LEDs or RGB LEDs, creating light patterns on keypads or chassis in a unique combination with backlighting. The driver extends battery life by adjusting the backlight current according to the ambient light level. Available in a 3×3×0.55-mm µQFN-16 package, the NCP5890 costs $1.30.
