Tue, 06/23/2009 - 4:44am

Designed to operate with products such as the ADP5520 lighting management system and ADP5588 mobile I/O expander, the ADP8860 LED backlight driver from ANalog Devices has ambient light sensing, a programmable register set, and fading and dimming, which combine to reduce power dissipation by up to 50 percent. Accepting an input from 1.7 V to 3.3 V, the device has a parallel configuration enabling the control of up to seven LEDs – six at 30 mA max and one at 60 mA. The LED drivers are available in 2 mm × 2.4 mm × 0.6 mm 20-bump WLCSP or 4 mm x 4 mm x 1 mm 20-pin LFCSP at $1.70 per unit in 1,000-unit quantities.
