  • Active-clamp flyback
  • The synchronous rectifier

White Paper Overview


The GaN technology opened up new approaches to meet the ever-increasing demand for high power density in adapters and chargers. While high-voltage GaN switches are commonly used, the potential of GaN on the secondary side has not been fully exploited yet.

In this white paper, you will:

  • Get the latest design tips regarding the usage of GaN in adapters and chargers
  • Read about the benefits of GaN devices used as SR switch
  • Discover the upsides and downsides of each of the following topologies:
  1. Conventional flyback
  2. QR-flyback
  3. Active-clamp flyback (ACF)
  4. Hybrid flyback
  • Get to know Infineon’s full GaN ACF evaluation board
