LT3477EFE in Linear Tech / ADI LT Series Family
The LT3477EFE family, manufactured by Analog Devices (formerly Linear Technology), consists of high-performance DC/DC converters specifically optimized for constant-current LED driving. These versatile regulators support boost, buck, and SEPIC configurations, providing engineers with significant architectural flexibility. With a 3A internal switch and a wide input voltage range, the family is designed to provide high-efficiency power conversion for high-brightness LEDs while maintaining precise current regulation through dedicated dual-current sense amplifiers.
Variants in This Sub-Family
Variants within the LT3477 sub-family primarily differ based on their thermal packaging and environmental grade certifications. The EFE suffix denotes the thermally enhanced 20-lead TSSOP package with an exposed pad for improved heat dissipation. Specific part numbers may also vary by temperature grade, such as the 'E' grade for standard operating ranges and the 'I' grade for extended industrial temperatures, and lead-free (PBF) status.
