gThe TDHBG2500P100 board can deliver 2500W with forced air cooling when
configured as
• 200V to 400V boost, 100kHz, or
• 400V to 200V buck, 100kHz
gDifferent input/output voltage and power can be chosen, however
• Input/output voltage should not exceed 400V
• In each GaN FET, the rms current should not exceed 9A
• Users should monitor the device temperature to make sure they are not being
overheated by excessive power during the test
gDriver deadtime is preset to 120ns for typical operation and can be adjusted
for different operating conditions; please refer to the TDHBG2500P100 User Guide
