LT3477IUF in Linear Tech / ADI LT Series Family
The LT3477IUF is a versatile 3A DC/DC converter family from Analog Devices (formerly Linear Technology) designed for high-performance current regulation. It features a unique dual-rail current sensing architecture that allows for both high-side and low-side sensing, making it an ideal choice for constant-current and constant-voltage applications. Operating over a wide input voltage range, it supports multiple topologies including Buck, Boost, and SEPIC, providing engineers with flexibility in power stage design for high-power LED strings and battery charging systems.
Variants in This Sub-Family
Variants within the LT3477 series primarily differ based on their thermal rating and package configuration. The LT3477IUF variant is specifically housed in a 20-lead 4mm x 4mm QFN package, offering a lower profile and better thermal dissipation compared to the TSSOP variants. The 'I' designation indicates an industrial temperature grade, rated for operation from -40°C to 125°C, ensuring reliability in harsh environmental conditions compared to standard commercial-grade counterparts.
