Tiny SEPIC reference design with 12-V/ 2.5-A output

This reference design is a 12-V pre regulator reference design for multiple automotive applications powering up to 36-W. The used SEPIC topology allows to step up and step down the input voltage, so cranking down to 5-V is supported; the controller LM5122 itself allows cranking down to 3-V at (...)
