The LT®3479 is a current mode, fixed frequency step-up DC/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. Through an external resistor, the user can program the switching frequency from 200kHz to 3.5MHz. The LT3479 is also available in a thermally enhanced 16-pin TSSOP package.
