Product Overview

The LT3479EFE#PBF is a 3A Full Featured DC/DC Converter with soft-start and inrush current protection. Efficiencies of up to 89% can be achieved in typical applications. It features a programmable soft-start function to limit inductor current during start-up and inrush current protection to protect the LT3479 during shorts and line transients. Both inputs of the error amplifier are available to the user allowing positive and negative output voltages. Through an external resistor, the user can program the switching frequency from 200kHz to 3.5MHz. The LT3479 uses a fixed frequency, current mode control scheme to provide excellent line and load regulation. Low ESR (equivalent series resistance) ceramic capacitors should be used at the output to minimize the output ripple voltage. Schottky diodes with their low forward voltage drop and fast switching speed, are ideal for LT3479 applications.
