The AAT1407IMK-T1 from Skyworks Solutions is a highly integrated LED backlight driver designed for applications such as notebook computers, monitors, and portable TVs. It features an integrated boost converter capable of delivering up to 45V output, suitable for driving series LEDs.
This device supports six precision current sinks, each programmable up to 30mA per string, with a total output current of 180mA. It offers flexible configurations, including disabling or paralleling LED strings for increased drive capability. The PWM dimming input supports frequencies up to 100kHz, providing a wide dimming range of up to 1,000:1 at 100Hz, which helps prevent audio interference.
The AAT1407IMK-T1 operates within an input voltage range of 4.5V to 26V and features a selectable boost switching frequency of 675kHz or 1.3MHz, allowing for optimized efficiency and smaller external filtering components. It includes fault-tolerant circuitry for open or shorted LEDs and over-voltage and over-temperature protection.
Packaged in a Pb-free, thermally enhanced 24-pin 3x4 TQFN package, this LED driver is designed for surface mounting. It operates across a temperature range of -40°C to +85°C.
