LT3477 - 3A, DC/DC Converter With Dual Rail-to-Rail Current Sense

The LT3477 is a current mode, 3A DC/DC Step-up converter with dual Rail-to-Rail Current Sense Amplifiers and an internal 3A, 42V Switch It combines a traditional voltage feedback loop and two unique current feedback loops to operate as a constant-current, constant-voltage source. Both Current Sense voltages are set at 100mV and CAN be adjusted independently using the IADJ1 and IADJ2 pins. Efficiency of up to 91% CAN be achieved in typical applications. The LT3477 features a programmable soft-start function to limit inductor current during start-up. Both inputs of the error Amplifier are available externally allowing positive and negative output voltages (Boost, Inverting, SEPIC, Flyback). The switching frequency is programmable from 200kHz to 3.5MHz through an external resistor. Available in thermally enhanced 20-pin (4mm 4mm) QFN and 20-pin TSSOP packages, the LT3477 provides a complete solution for both constant-voltage and constant- current applications.
