Description

The PMP9638 reference design uses the UCC28740 Flyback with resonant-ring valley-switching controller to generate dual DC output 12V/2A and 3.3V/0.5A from a universal AC input. This design minimize switching loss in FET to provide high efficiency. The current regulation feature of the UCC28740 provides accurate current limit protection.

Features
  • Universal input 85 -264VAC
  • Dual outputs
  • Output constant voltage and constant current mode hold up time for outputs
  • Lower Switching loss
