Description

This reference design is a compact and thermally efficient design intended to be used as a bias supply for half-bridge converters. A DCM Flyback with UCC3813-4 controller is used to generate two isolated 12V supplies for half-bridge converter primary driving circuitry. One 5V is generated at the secondary side for secondary rectifier driving circuitry and controller. The second winding at secondary side can be used to sense input voltage level while the Flyback converter is operating.

Features
  • 200VDC to 400VDC input, two isolated 12V output at primary side and one 5V output at secondary side
  • Less than 30 degree C temperature rise on all parts
  • Input voltage sensing circuit included
  • 1" x 1.5" x 0.5" board dimension
  • Test report available
