Key Document

Description

The PMP30198 reference design uses the UCC28910 flyback controller with integrated MOSFET to generate two isolated outputs (18V@0.25A / 18V@0.04A) from an AC input. The UCC28910 implements primary-side regulation, eliminating the need for an opto-coupler and reducing the total component count.

Features
  • Isolated outputs
  • Primary-side regulated
  • Valley switching
  • Integrated MOSFET
  • Test report available
