The Case for GaN HEMTs in Class-D Audio
Class‑D audio amplifiers are overtaking linear topologies as efficiency demands rise across consumer, professional, and automotive markets. While silicon MOSFETs have traditionally handled the high‑speed switching, their parasitic capacitances and body‑diode recovery limit performance at higher frequencies. Gallium‑nitride (GaN) high‑electron‑mobility transistors (HEMTs) offer dramatically lower gate charge and faster switching, cutting losses up to tenfold and enabling operation near 1 MHz. The EPC‑9192 demo board showcases these gains, delivering over 96% efficiency at 700 W per channel with pristine audio fidelity.
