Audio Eval Board Enlists GaN Power Transistors

GaN Systems’ Evaluation Board employs what it calls the world’s fastest combination of GaN power transistors and power drivers. Combining best-in-class GaN transistors with the fastest commercially available GaN transistor driver on the GS61004B evaluation board, the GS61004B-EVBDC evaluation platform is now available with the latest in high-speed GaN E-HEMT drivers from Peregrine Semiconductor.


The evaluation kit (GS61004B-EVBDC) combines GaN Systems’ GS61004B power transistors with the fastest GaN transistor driver available – the PE29102 - from Peregrine Semiconductor. This combination on the GS61004B-EVBDC evaluation platform provides power design engineers with desirable features that include:


Sensors 2018 Hits Silicon Valley June 26-28!

Join thousands of engineers this June in San Jose at the sensor industry’s biggest event! With 65+ Technical Sessions, 100+ Leading Speakers, and 300+ Interactive Exhibits, there’s more opportunity than ever to connect with this booming industry and the technologies driving it. See thousands of the newest technologies in action, learn about the latest applications, including AI, Autonomous Vehicles, IoT, and Medical, and develop invaluable partnerships at the only event dedicated to sensors, connectivity, and systems.


  • Four GS61004B GaN transistors and two PE29102 E-HEMT drivers
  • GaN transistors operable up to 100 MHz
  • Transistor driver operable up to 40MHz
  • Best-in-class propagation delay
  • Optimized, Vcc independent, for matched dead time
  • Integrated dead-time control, resistor-adjustable


The GS61004B GaN E-HEMTs used in conjunction with the PE29102 high-speed GaN E-HEMT Driver, generate low dead times to minimize crossover distortion in class-D applications. The PE29102’s unique set of phase-control pins enable the same part to be used for both phases in bridge-tied load (BTL) configurations—a technique used in audio amplifiers.


The evaluation platform includes a GaN E-HEMT Driver GS61004B Full-Bridge evaluation board assembly and detailed User’s Guide. The GS61004B-EVBCD is priced at $99 each. GaN Systems Inc. Ottawa, Ontario, Canada. 613-686-1996 and [email protected]
