TransphormHighest Performance, Highest Reliability GaN


Half-bridge Daughter Card Power Stage used in the Synchronous Buck or Boost Evaluation Platform (TDHBG1200DC100-KIT)

The TDHB-65H070L-DC half-bridge power stage daughter card provides the elements for basic study of switching characteristics and efficiency achievable with Transphorm’s 650V GaN FETs. It is also part of the evaluation board (TDHBG1200DC100-KIT) and can operate in either synchronous boost or buck mode with a high-voltage input and output of up to 400Vdc, with a power output of up to 1.2 kW.
