🛠️ Technical Deep Dive
• Switching Frequency & Efficiency: GaN enables higher switching frequencies than silicon, reducing conversion losses and thermal dissipation requirements; this is fundamental to achieving 97.5% peak efficiency in AI data center PSUs[2][4] • Power Density Architecture: GaN devices support planar transformers and higher-density CRPS (Common Redundant Power Supply) form factors, allowing more GPUs per rack without exceeding thermal limits[2][4] • Voltage Optimization: GaN on silicon substrate is optimal for 650V-800V range (standard in 2026 EV architectures); vertical GaN technology remains under assessment due to smaller wafer sizes and cost disadvantages[3] • Manufacturing Scaling: Infineon's transition to 300mm wafers achieves 2.3x higher chip yield versus 200mm competitors; 100V devices sampled late 2025 with production expected end-2026 or early 2027[3][4] • Thermal Management Integration: Compact GaN-based designs reduce cooling requirements and free board space in AI servers, enabling more efficient power conversion at the PSU and IT (low-voltage switch) stages[5]
