ANALOG DEVICES LT3758EDD#PBF

LT3758 is a wide input range, current mode, DC/DC controller which is capable of generating either positive or negative output voltages. They can be configured as either a boost, flyback, SEPIC or inverting converter. The LT3758 drive a low side external N-channel power MOSFET 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 LT3758 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 5.5V, and a low shutdown quiescent current of less than 1µA, make the LT3758 ideally suited for battery powered systems. The LT3758 feature soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit.
