Description

his reference design uses the UCC28730-Q1 flyback controller to produce an isolated 15-V output. The design is capable of 0.33 A from a 40-V to 250-Vdc input and 1 A from a 250-V to 550-Vdc input. This power system is designed for an inverter bias supply application and is an automotive-qualified solution.

Features
  • Wide 40-V to 550-V input voltage range
  • Isolated 15-V output with 1-A maximum current
  • Peak efficiency of 86%
  • Automotive-qualified solution
