108-VDC - 411-VDC Input non-isolated flyback reference design

Design files

Overview

This offline flyback reference design uses the UCC28910 controller to generate 2 non-isolated outputs (6.5 V at 600 mA, 15 V at 67 mA) from a DC input (108 VDC - 411 VDC). The UCC28910 incorporate a 700-V power FET and a high-voltage current source for startup to achieve low stand-by power. The valley-switching technique reduces switching losses and keeps the efficiency high. The controller provides constant-voltage and constant-current regulation without the use of an optical-coupler.

Features
  • 108 VDC - 411 VDC input to two non-isolated outputs
  • Primary-side regulation eliminates the need for an optical coupler
  • Valley-switching operation keeps the efficiency high
  • Easy to use because of integrated 700-V power FET
