The AAT1405 is a high efficiency four LED strings backlight driver optimized for notebook computers, monitors and portable TVs. The integrated boost converter and precision current sinks operate from DC inputs, cigarette lighter adapters, or multi-cell Li-ion batteries over the 4.5V to 26V voltage range. The AAT1405 drives up to 44 LEDs at 120mA total LED current. The high (100 kHz) PWM frequency ensures silent operation.
