Description

The PMP8502 reference design uses the UCC28701 quasi-resonant flyback converter to generate an isolated output (5V @ 1.6A). It is a low cost solution because no optocoupler is needed to regulate the output voltage.

Features
  • Wide AC input range (150VAC - 400VAC)
  • Over current, over voltage and short-circuit protected
  • Test report available
