650 V GaN E-HEMT Daughter Board

Utilize with any ON Semiconductor controller IC eval board

The GS-EVB-HB-66508B-ON1 evaluation board consists of NCP51820 gate drive solution with two GS66508B GaN E-HEMT’s in a fully-functional Half-Bridge. It allows users to easily evaluate GaN in an ultra- small layout with NCP51280 gate driver, for a highly cost-effective solution.

Applications and Benefits:

  • AC-DC Adapters for Mobile, OLED TV, Gaming
  • Datacenter power supplies, PV Inverters/ESS
  • Bridgeless Totem Pole PFC, LLC, ACF, ZVS
  • Highly-integrated Half-Bridge Driver in QFN 4×4 creates ultra-small GaN gate drive layouts
  • 1MHz operation and 200 V/ns CMTI allows high power density GaN-based system designs

Created in partnership with ON Semiconductor, featuring NCP51820, a high voltage Half-Bridge gate driver
