LT3479EFE#PBF Description

Short technical summary and product information.

The LT3479EFE#PBF is a current mode, fixed frequency step-up DC/DC converter featuring an internal 3A, 42V switch. It is designed for high efficiency power conversion, achieving up to 89% in typical applications. The device includes 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 wide input voltage range of 2.5V to 24V makes it versatile for numerous applications. The switching frequency can be programmed externally from 200kHz to 3.5MHz, allowing for design flexibility. The LT3479EFE#PBF is available in a low profile 14-pin DFN package (4mm x 3mm) and a 16-pin TSSOP package, both offering excellent thermal performance.

 

Key features include protection against input short circuits and hot plugging, and a low VCESAT switch (0.3V at 2.5A typical). It is capable of producing both positive and negative output voltages, making it suitable for applications such as high power LED drivers, DSL modems, and distributed power systems.
