Description

This design features the UCC28730 flyback controller in conjunction with the UCC24650 wake-up monitor to provide CV, CC regulated output with ultra-low stand-by power that exceeds Level VI and CoC Tier 2 specifications for average efficiency and 10% load efficiency.  Wake-up signal detection provides fast transient response to large load steps.

Features
  • No-Load Stand-By Power Consumption less than 5 mW
  • Wake-Up Detection for Fast Dynamic Response
  • Primary Side Regulation Eliminates Opto-Coupler
  • Average Efficiency > 83%; exceeds Level VI and CoC Tier 2 specifications, effective 2016
  • 10% efficiency > 80%
  • Resonant Ring Valley Switching Operation for Highest Overall Efficiency
