The LT3757 and LT3758 are wide input voltage range multi-topology highly versatile DC/DC controllers that can be designed into boost, flyback, SEPIC and inverting power supplies. Both parts can regulate either a positive or negative output voltage thanks to their two on-chip references and error amplifiers. These parts have programmable soft start and a very low and accurate current sense threshold that maximizes efficiency and provides a very predictable over current trip point. Additionally, powerful on-chip MOSFET drivers allow output currents of up to 10A.
