16 Channel White LED Driver Solution with LED Current and Timing Control
General Description
The AAT2430B is a highly integrated, high efficiency white LED backlight solution for large size LCD panels used in LCD TVs. By controlling external power MOSFETs (such as the Skyworks' AAT2491 high-voltage TrenchDMOS array), the AAT2430B facilitates 16 current sink channels to provide precision constant-current drive for strings of white LEDs, where the number of series-connected LEDs per string is only limited by the system LED voltage supply. Current in each backlight string and string-to-string matching is controlled using I-Precise™ sensing and control circuitry, a...
