LMG3410-HB-EVM: LMG3410-HB-EVM operation frequency limit

Part Number: LMG3410-HB-EVM

Good day Colleagues,

The LMG3410-HB-EVM user guide page 11 says test frequency is 50 to 250kHz.

Are there any limitations for higher operation frequency and if yes, what are they?

My customer wants to test the board at 350kHz.

Thank you, Mike

  • Hello Mike,

    The limitation here should be the thermal of the device. If customer can provide adequate active cooling on the device, they should be able to switch at 350kHz. To be safe, please ask customer to put a thermocouple on the device and make sure the temperature is under 125 degree C (under 110 for safe operation). 

    Device itself will be limited to around 1 Mhz due to the maximum current that is able to supply to the gate.
