Power Integrations, Inc. LED Drivers IMX101J-TL

The IMX101J-TL is a constant voltage and four-channel dimming LED backlight controller from Quarktwin Technology Ltd. It features one constant voltage output and supports up to four LED strings, providing a maximum total string current of 960 mA and a string voltage of up to 100 V. The device offers excellent transient response with a ±5% output voltage variation during load changes and includes multiple dimming options such as analog, PWM, sequenced PWM, and filtered PWM. The IMX101J-TL is designed to enhance system efficiency by eliminating the need for buck and boost converters, achieving up to 91% efficiency in a compact PCB footprint. It incorporates advanced protection features, including individual overload protection for each output and safeguards against string imbalances, shorts, and open circuits. The product is available in a 28-lead QFN package, suitable for multilayer designs. This controller is particularly applicable for ENERGY STAR compliant monitors and TVs, making it a viable option for engineers looking to implement efficient LED backlighting solutions.
