Overview
PRODUCT SUMMARY AAT2430A-1 Sixteen-Channel White LED Driver Solution with LED Current and Timing Control General Description The AAT2430A-1 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 AAT2430A-1 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 novel on-chip method to accurately control drain current in external discrete power MOSFETs independent of their construction and without the need for precision sense resistors.
A 15MHz SPI compatible interface allows fast, independent digital control of each current sink.
