PMP9689

Design files

Overview

The PMP9689 reference design uses the UCC28910 primary-side regulated flyback controller with integrated MOSFET to generate a 5V/0.3A output from an univeral AC input for metering applications.

Features
  • Wide Vin capability (85Vac to 265Vac)
  • Lower component count
  • High level of integration
  • Lower cost – Opto coupler eliminated
