Charge pump WLED drivers

California Micro Devices added a compelling and differentiated family of fractional charge pump WLED drivers to its PhotonIC family of white LED drivers for wireless handset applications. With increased demand for brighter and larger resolution displays, powerful camera flash capabilities for multi-megapixel camera resolutions and various types of LEDs to support keypad backlight and multimedia capabilities, wireless handset designers have become increasingly concerned with the efficiency of the LED driver subsystem.
The PhotonIC family of white LED drivers now includes five current regulated fractional charge pump products (CM913x/4x) that can drive up to six WLEDs, as well as three voltage regulated products (CM915x). All these products feature a simple analog control interface as well as optimal efficiency in a compact footprint.

Both product families suit driving backlights, keypad and camera flash LED sub systems in the most efficient way in a compact footprint and at the lowest bill of materials.
