The LT3479EDE#PBF from Analog Devices is a versatile step-up DC/DC converter designed for high efficiency power conversion. It features a 3A, 42V internal switch and can achieve efficiencies up to 89% in typical applications. The converter operates with a wide input voltage range of 2.5V to 24V and supports adjustable output voltages, capable of producing both positive and negative outputs.
Key features include a programmable soft-start function to limit inductor current during start-up and inrush current protection for enhanced reliability during shorts and line transients. The switching frequency can be programmed externally from 200kHz to 3.5MHz, allowing for optimization of component size and performance. The device is available in a low profile, thermally enhanced 14-lead DFN package (4mm x 3mm) and a 16-lead TSSOP package, providing excellent thermal performance in a compact footprint.
This DC/DC converter is suitable for applications such as high power LED drivers, DSL modems, and distributed power systems. Its robust design includes protection against input short circuits and hot plugging, making it a reliable choice for demanding power management solutions.
