REF_3K3W_HFHD_PSU is a 3.3 kW, 95 W/in³ power supply for server and telecom using GaN, SiC and Si devices. The front-end AC-DC converter is a two-phase SiC interleaved bridgeless totem-pole stage for power factor correction, while the high-frequency (500 kHz) DC-DC converter to provide isolation and regulate output voltage is a GaN LLC half-bridge, with full-bridge rectification. The PSU includes a baby-boost stage to hold-up time requirements.Be the first to receive this board. Pre-order here.

Features

  • 97.4% efficiency @95 W/in³
  • High frequency GaN LLC design (500 kHz)
  • Fully integrated transformer structure
  • 2-ph interleaved totem-pole SiC AC-DC 

Benefits

  • Infineon solution using GaN, SiC and Si 
  • Highest efficiency and power density
  • Digital control for both converters
  • Hold up time extension circuit
