REF_3K3W_3LFC_PSU is a 3.3 kW high-frequency and high-density PSU for server telecom applications. The front-end AC-DC converter is a 3-level flying capacitor (3LFC) implemented with 400 V CoolSiC™ 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.

Features

  • 97.6% Peak efficiency @ 98 W/in³
  • 3-level flying capacitor PFC
  • High frequency GaN LLC (500 kHz)
  • Fully integrated transformer structure

Benefits

  • System solution using GaN, SiC and Si
  • OCP efficiency spec incl high p. density
  • Flying cap. charge solution at start-up
  • S3-level driving supply
  • Hold-up time extension circuit
