Solutions Power Management Switching Regulator Flyback, Forward and Isolated Controllers

DC894C-C - LT3825EFE Isolated Demo Board | Sync No Opto Flyback Controller, 36V ≤ VIN ≤ 72V; VOUT = 12V @ 5A

Demonstration circuit 894C-C is a 36V-72Vin, synchronous flyback converter featuring the LT3825. This circuit was designed specifically to attain a high current, low ripple, synchronously rectified flyback to efficiently power 12V loads at up to 5A from a typical telecom input voltage range. This circuit features synchronous rectifier drive outputs, output voltage regulation without the need of an optocoupler, self-starting architecture and input undervoltage lockout.
