说明
- DC1961A, Demonstration Board using LT8309 secondary synchronous driver in an isolated, no optocoupler, flyback converter. It regulates a 12V, 5A output from a 36V to 72V input source. Output regulation is handled on the primary side by the LT3748, a boundary conduction mode flyback controller which senses output voltage directly from the primary, resulting in a simple flyback schematic with no Optocoupler. The LT8309 synchronous rectifier driver replicates the behavior of a diode by sensing the synchronous MOSFET drain-to-source voltage to determine its turn on period
