The LT3958EUHE#PBF is a high input voltage, Boost, Flyback, SEPIC and inverting DC/DC Converter capable of generating either positive or negative output voltages. It features an internal low side N-channel power MOSFET rated for 84V at 3.3A and driven from an internal regulated 7.2V supply. The fixed frequency, current-mode architecture results in stable operation over a wide range of supply and output voltages. The operating frequency of LT3958 can be set with an external resistor over a 100kHz to 1MHz range and can be synchronized to an external clock using the SYNC pin. A minimum operating supply voltage of 5V and a low shutdown quiescent current of less than 1μA make the LT3958 ideally suited for battery-powered systems. The LT3958 features soft-start and frequency fold back functions to limit inductor current during start-up.
