The LT®3757 is a wide input range, current mode, DC/DC controller which is capable of generating either positive or negative output voltages.
It can be configured as either a boost, flyback, SEPIC or inverting converter.
Key Features
soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit. The device is available in a small 10-lead DFN (3mm × 3mm) or MSOP package.

a wide input range, current mode, DC/DC controller which is capable of generating either positive or negative output voltages. It can be configured as either a boost, flyback, SEPIC or inverting converter. The LT3757 drives 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 LT3757 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 low minimum operating supply volta
