Features n LT3825 Isolated No-Opto Synchronous Flyback Controller with Wide Input Supply Range DESCRIPTION The LT®3825 is an isolated switching regulator controller designed for medium power flyback topologies. A typical application is 10W to 60W with input voltage limited only by external power path ponents. A third transformer winding provides output voltage feedback. The LT3825 is a current mode controller that regulates output voltage based on sensing secondary voltage via a transformer winding during flyback. This allows for tight output regulation without the use of an optoisolator, improving dynamic response and reliability. Synchronous rectification increases converter efficiency...
