GaN Systems’ GS-EVB-AUD-xx1-GS Audio Eval Boards, Now at Mouser, Deliver High-Performance, Low-Cost Audio System

by donpedro

Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the new GS-EVB-AUD-xx1-GS audio EVB platform from GaN Systems. The highly efficient evaluation platform features a Class D amplifier and companion power supply optimised for sound quality, thermal performance, cost, and size. Together, the boards provide an exceptional reference design for the development of a low-cost, high-performance audio system.

The GaN Systems GS-EVB-AUD-xx1-GS platform, available from Mouser Electronics, is available as a Class D amplifier board only (GS-EVB-AUD-AMP1-GS) or bundled with a switch-mode power supply (SMPS) board (GS-EVB-AUD-BUNDLE1-GS). The audio evaluation platform delivers outstanding sound quality through increased bandwidth and reduced total harmonic distortion. The integrated Class D amplifier features a two-channel, stand-alone, bridge-tied-load design with support for extendibility and scalability. The versatile amplifier is capable of switching between open-loop and closed-loop designs with optimised DSP control of each configuration. The Class D amplifier features an output power of 75 W to 250 W, while the companion SMPS offers an output power of 400 W and is scalable to 500 W. The SMPS also features a split rail output and incorporates an EMI/EMC filter.

Both the Class D amplifier and the SMPS boards include GaN Systems’ enhancement-mode high electron mobility transistors (E-HEMTs). The E-HEMTs incorporate GaN Systems’ Island Technology® cell layout to reduce both the device size and cost, while delivering substantially higher current and better performance than other GaN devices. The GaN Systems GS61008P, implemented in the Class D amplifier, is a bottom-side-cooled 100 V, 90 A E-HEMT that can be easily driven directly from a variety of GaN drivers. The GaN Systems GS66506T, implemented in the SMPS, is a top-side cooled 650 V, 22.5 A E-HEMT that is easy to drive from standard PFC and LLC controllers. Both transistors offer fast switching, zero reverse recovery charge, and low output capacitance.
