The LT3477EFE#PBF is a current-mode step-up DC-to-DC 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.
● Up to 93% high efficiency power conversion
● Drives LEDs in boost, buck-boost or buck mode
● Programmable soft-start
● 100mV Dual rail-to-rail current sense amplifiers
● 0.3V at 2.5A Low VCESAT switch
