AAT1407 - Six-Channel LED Backlight Driver

Key Features

  • The AAT1407 is a highly integrated, high efficiency LED backlight solution for notebook computers, monitors and portable TVs. The device operates from DC inputs, cigarette lighter adapters, or multi-cell Li-ion batteries over the 4.5V to 26V voltage range. An integrated boost (step-up) converter provides up to 45V output for driving series LEDs. Six precision current sinks are programmed up to 30mA per string through one external RSET resistor, supporting up to 661 white LEDs at 180mA total out.
