LT3757 Boost, Flyback, SEPIC and Inverting Controller - Video Product Brief

Kevin B. Scott - Senior Strategic Marketing Engineer Jun 4th 2010

The LT3757 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 controller. 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 LT3757 features soft-start and frequency foldback functions to limit inductor current during start-up and output short-circuit.
