GaN Systems GS-EVB-AUD-BUNDLE2-GS Audio Class-D Amplifier and SMPS Development Kit

The GaN Systems GS-EVB-AUD-BUNDLE2-GS bundle comprises the GS-EVB-AUD-AMP2-GS audio class-D amplifier board and the GS-EVB-AUD-SMPS2-GS Switched-Mode Power Supply (SMPS) board. These designs are optimised for sound quality, thermal performance, size, and cost for a fan-less solution that achieves extremely high efficiency, high power density, and reliable start-up, with no heat sinking, low THD, and low EMI.

The GS-EVB-AUD-AMP2-GS amplifier board provides 200 W per channel into 8 Ω or 300 W per channel into 4 Ω with a full-load efficiency >96%, and it is configured to allow for both ‘open-loop’ and ‘closed-loop’ operations, with various standard audio source inputs. This board is driven by the GaN Systems GS61008P, a bottom-side cooled 100 V, 90 A E-HEMT that can be easily driven directly from a variety of GaN drivers. With GaN Systems’ packaging innovations, this device offers very low junction-to-case thermal resistance, low inductance, and very-high-efficiency power switching (>10 MHz) for demanding high-power applications.

The GS-EVB-AUD-SMPS2-GS SMPS board operates on a universal AC line input voltage of between 85 V and 264 V and provides a ±32 VDC regulated output voltage. The design is capable of 400 W continuous output power with a full-load efficiency >90%. The SMPS is controlled by advanced digital control methods coupled with 650 V GaN enhancement mode E-HEMTs, the GaN Systems GS-065-030-2-L and GS-065-011-2-L, which offer the same advantages of GaN as the GS61008P but with smaller maximum currents, 30 A and 11 A respectively, and a lower maximum switching frequency of >1 MHz.

When applying for this kit, feel free to specify whether you only require the amplifier or SMPS board.
