Evaluation kit showcases Peregrine GaN FET driver

Featured Product from Richardson RFPD


Peregrine's UltraCMOS® PE29102 high-speed FETdriver brings the industry's fastest switching speeds to Gallium Nitride (GaN) Class-D audio. With a switching frequency up to 40 MHz, the PE29102 delivers the industry's fastest switching speeds, empowering design engineers to extract the full performance and switching speed advantages from GaN transistors. In class-D audio amplifiers, this new high-speed FET driver enables GaN technology to delivery superior audio performance with low jitter.

Audio systems are challenged to both minimize size and deliver exceptional audio quality to listeners. At the system-design level, better audio performance and sound quality occur when distortion is reduced. MOSFET components have parasitic diodes and gate capacitance that creates jitter and distortion in class-D audio systems, whereas GaN FETs have much smaller gate capacitance and lower parasitics. GaN transistors can beat MOSFET jitter performance by a factor of ten and deliver reduced distortion and smooth sound. However, to reach this performance potential, GaN transistors need an optimized gate driver. The PE29102 is designed specifically for this purpose. Its high switching speeds result in smaller peripheral components and enable innovative designs for applications like class-D audio.

Peregrine's UltraCMOS technology platform is the driving force behind the PE29102's industry-leading speeed. This technology enables integrated circuits to operate at much faster speeds than conventional CMOS technologies. This speed advantage results in significantly smaller power converters, which benefits the design engineer with increased power density. 

To showcase the GaN-enabling capabilites of this driver, Peregrine developed an evaluation kit with leading GaN transistor provider GaN Systems.

The GaN Systems GS61004B evaluation board allows the user to evaluate the PE 29102 gate driver in full-bridge configuration. The evaluation board is assembled with two PE29102 FET drivers and four GS61004B GaN transistors. The full bridge board is available from Richardson RFPD as part number EK29102-03.
