LT3743EFE Description

Short technical summary and product information.

The LT3743EFE is a high current synchronous step-down LED driver manufactured by Analog Devices. This component is designed for efficient power management in LED lighting applications. It features a wide input voltage range of 6V to 36V and can deliver an output voltage of up to 30V.

 

Key electrical characteristics include a typical output current of 20A and a high dimming ratio of up to 3000:1, achievable through both PWM and CTRL_SEL dimming methods. The device offers ±6% current regulation accuracy and an average current mode control for precise current management. It also boasts a fast recovery time of 2µs between current regulation states.

 

The LT3743EFE is available in a 28-lead TSSOP with exposed pad (EP) or a 28-lead QFN package measuring 4mm x 5mm with an exposed pad. It operates within a temperature range of -40°C to 125°C. This LED driver is suitable for applications requiring high-current LED driving with precise control and dimming capabilities.
