Abstract—Purpose of this paper is to describe the hardware design implementation of synchronous fly back converter featuring the LT3825. This circuit was designed specifically to attain a high current, low ripple, synchronously rectified fly back to efficiently power 3.3V loads at up to 12A from a typical telecom input voltage range36V-72V. This circuit features synchronous rectifier drive outputs, output voltage regulation without the need of an opto-coupler, self-starting architecture and input under voltage lockout.
Index Terms—synchronous fly back converter, switching regulator, inrush current, load compensation, under voltage lockout, soft-start circuitry, orcad
