描述
This reference design is a half bridge LLC resonant converter, typically combined to PFC front end. It works directly from mains (100 VAC - 127 VAC) and supplies 38 V at 2 A. The burst mode feature keeps the curve flat in a range of 86% - 94% when load is varied between 1% and 100%.


特性

  • Compact and highly efficient 75-W isolated converter with synchronous rectification
  • Integrates HV primary side gate drivers; no need for external gate drive transformer
  • Compliant with most stringent global efficiency standards with efficiency > 93% from 10% to full load
