The LT3479EDE#PBF is a current-mode fixed frequency step-up DC-to-DC Converter with an internal 3A/42V switch. 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.
● Protection against input short-circuit and hot plugging
● Capable of positive and negative outputs
● 0.3V at 2.5A Typical low VCESAT switch
