TransphormHighest Performance, Highest Reliability GaN


2.5kW Totem-pole PFC GaN Evaluation Platform

The TDTTP2500P100 2.5kW bridgeless totem-pole power factor correction (PFC) evaluation board achieves very high efficiency single-phase AC-DC conversion. Using GaN FETs in the fast-switching leg of the circuit and low-resistance MOSFETs in the slow-switching leg of the circuit results in improved performance and efficiency. The TDTTP2500P100-KIT is for evaluation purposes only.


  • Power: 2500W
  • Switching frequency: 100kHz
  • Features TPH3212PS
  • Easy-to-use platform to investigate GaN


  • Data center power supply
  • Broad industrial power supply
