AAT2405 Description
The AAT2405 is a highly integrated, high efficiency white LED backlight solution for large size LCD panels used in LCD TVs. This device operates from a wide 10.8V to 28V DC power source, making it ideal for operation with mon 12V to 24V AC-DC power supplies used in LCD TV panels. By controlling external power MOSFETs (such as the Skyworks' AAT2490 high-voltage TrenchDMOS array), the AAT2405 facilitates 6 current...
