Description

An isolated flybuck converter with self-driven synchronous rectification on the secondary side accepts an input voltage of 10.8Vin to 13.2Vin and provides an isolated output of 5Vout capable of supplying a maximum of 0.3A of current to the load.

Features
  • Excellent regulation 4.9Vout ± 3.1% over entire line and load range without opto or discrete Vref
  • No need for pre-load on isolated output, without output voltage rise at light load
  • Improved load regulation, smaller voltage droop at heavy load
  • LM5017 wide Vin range 7.5V to 100V
  • Easy-to-design, cost effective Fly-Buck solution
  • Constant On-Time control, no loop compensation required
