DataSheet.in PRODUCT DATASHEET AAT1409 SwitchRegTM 8 Channel LED Backlight Driver with Integrated Boost and High Frequency Direct PWM Dimming General Description The AAT1409 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. Eight precision current sinks are programmed up to 45mA per string through one external RSET resistor, supporting up to 881 white LEDs at 360mA total output current. LED strings may be disabled or operated in parallel for increased drive capability.
