Dual charge pump simplifies handset
power
A novel multifunction high-efficiency dual charge pump supports both white LED backlight and camera flash applications for portable systems that run on lithium batteries.
Many of today's handsets feature two displays, either in a clamshell design with a main display on the inside and a secondary display on the outside or in a bar design with a main display and a keypad backlight By combining independent control of two separate banks of backlight LEDs with flash capability and a light load mode in a single device, AnalogicTech's AAT2803 charge pump helps designers minimise power consumption while reducing component count and package size
