Original Press Release:

Richardson RFPD Introduces GaN Systems’ New High-Performance Buck Converter Evaluation Board with Integrated pSemi High-Speed Driver

Collaboration between GaN Systems and pSemi is designed for optimal performance at high switching speeds and offers shorter time-to-market

June 5, 2018 – Geneva, Ill.: Richardson RFPD, Inc. announced today the availability and full design support capabilities for a new evaluation board from GaN Systems Inc. and pSemi Corporation.

The GS61008P-EVBHF 100 V buck converter evaluation board allows the user to evaluate GaN Systems’ 100 V GS61008P E-Mode GaN transistor with the pSemi PE29101 gate driver in a half-bridge configuration. The PE29101 integrated high-speed driver is designed to control the gates of GaN Systems’ E-HEMTs. The outputs of the PE29101 can provide switching transition speeds in the sub-nanosecond range.

The new evaluation board’s high switching speeds enables smaller peripheral components in a variety of applications, including DC–DC conversion, AC–DC conversion, wireless power charging, and LiDAR.

Additional key features of the GS61008P-EVBHF include:

  • Universal GaN half-bridge with open loop control
  • Ultra-fast switching times: < 1 ns
  • Dead-time control, independent of Vcc
  • 100 V / 90 A, 7 mΩ GaN E-HEMTs
  • High-speed GaN driver, capable of 40 MHz
