GaN Systems Announces MHz Eval Board

News

GaN power transistor board is for applications as diverse as audio speakers, lasers, DC-DC converters and wireless chargers

GaN Systems has announced the availability of a new evaluation board using what it believes is the world's fastest combination of GaN power transistors and power drivers.

The evaluation kit (GS61004B-EVBDC) combines four of GaN Systems' GS61004B power transistors with two of Peregrine Semiconductor's fastest GaN transistor driver available - the PE29102. The GaN transistors are operable up to 100 MHz and the transistor drivers up to 40MHz.

The board is for applications as diverse as audio speakers, lasers, DC-DC converters and wireless chargers, that can use precise, megahertz pulses of energy to their intended loads.

The GaN E-HEMTs used in conjunction with the PE29102 driver, generate low dead times to minimise crossover distortion in class-D applications. The PE29102's 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.

Commenting on this development, Paul Wiener, VP strategic marketing for GaN Systems stated: “By providing an evaluation kit with GaN Systems' world's best power transistors and Peregrine Semiconductor's fastest-ever GaN transistor driver, design engineers have an easy-to-use platform for optimising their system's performance and gaining a competitive advantage. GaN Systems is pleased to provide yet one more tool that makes it easy to design with GaN transistors.”

“By enabling GaN to reach its performance potential, UltraCMOS technology and Peregrine are playing a role in GaN's disruption into more mainstream applications,” says Mark Moffat, director of Peregrine's power management product line. “In the case of audio, GaN technology is enabling the next-generation of class-D audio advancements, and Peregrine is proud to enable GaN in audio and beyond.”

The GS61004B-EVBDC evaluation platform is available worldwide through distribution channels. The evaluation platform includes a GaN E-HEMT Driver GS61004B Full-Bridge evaluation board assembly and user's guide.
