Overview

This design uses the UCC28610 quasi-resonant flyback controller to generate 3 isolated outputs from an universal input (90VAC - 290VAC). It was built on a low cost single layer PCB. The regulated output provides 12V@1.89A and the maximum output power is 33W.

Features
  • Universal input voltage
  • Valley switching
  • Multiple outputs
  • Single Layer PCB
