Description

This reference design is a 120Vac to 5V primary side regulated flyback converter with synchronous rectification on the secondary side. PMP11500 has built in cable compensation  which adjusts the regulation set point to offset the resistance in long cables. The reference design has extremely low standby power and its wake-up detection scheme offers superior transient response. UCC28730 features integrated CCCV regulation without the use of an optocoupler. PMP11500 utilizes synchronous rectification which improves system efficiency across the designed load range.

Features
  • 22mW standby power
  • Built-in cable compensation to offset cable resistance
  • Wake-up detection offers superior transient response
  • Synchronous rectification improves system efficiency
  • Constant-current, constant-voltage regulation
