10.8Vin~13.2Vin: 5Vout @ 300mA: Isolated Self-Driven Synchronous Flybuck Converter Reference Design

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 VrefNo need for pre-load on isolated output: without output voltage rise at light loadImproved load regulation: smaller voltage droop at heavy loadLM5017 wide Vin range 7.5V to 100VEasy-to-design: cost effective Fly-Buck solutionConstant On-Time control: no loop compensation required
