AAT2400/2401
Sixteen-Channel White LED Driver Solution with Full LED Current and Timing Control
General Description
The AAT2400/2401 is a highly integrated, high efficiency white LED backlight solution for large size LCD panels used in LCD TVs. To acmodate power requirements, the solution consists of two devices, a master device (AAT2400) and a slave device (AAT2401). The devices operate from a regulated 24V DC power supply. The master device supplies a 40V rail to drive 10 series LEDs with a typical VF of 3.6V. 16 precision current sinks split evenly between the master and slave devices provide constant current drive for up to 160 white LEDs.
