Isolated 53V/400mA Output Flyback Solution Reference Design Featuring the LM3481

PMP10723 is an isolated output flyback solution that accepts an input voltage of 9 VIN to 16 VIN and provides a 53-V/400-mA output. With secondary control, it can achieve great load regulation performance. Also it can fan out to cover other isolated high-voltage applications just by changing the (...)
