ADP8870, Parallel Backlight Driver
The ADP8870 combines a programmable backlight LED charge-pump driver with automatic phototransistor control of the brightness (LED current) and a PWM input to control the scale of the output current.
This combination allows significant power savings because it automatically changes the current inten
