Isolated Non-synchronous Flyback Converts Universal Vin to 18V@550mA Reference Design

Description

The LM5021-2 is an off-line controller that can work in CCM and DCM. A pulse skip mode improves the efficiency of this isolated flyback: and flattens the curve at most loads. It is also suitable for power line communication PSU.

Features
  • Ability for the power supply to work in both CCM and DCM modeWide Vin capability (90 to 275V AC)Duty cycle restriction to 80%84% full load efficiency and over a wide range of loadGives the user the flexibility to do external slope compensation with LM5021-2
