Buck converter evaluation board with integrated high-speed driver

Richardson RFPD has announced the availability and full design support capabilities for a new evaluation board from GaN Systems 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

The benefits of replacing plain old paper with e-paper displays in automotive assembly plants
Efficiency is at the heart of automation, and that is nowhere more apparent than in the manufacture of automobiles. The Ford Motor Company is widely credited with inventing the moving assembly line, but the concept of moving the assembly, rather than the worker, dates back centuries.
