LMR33640: SW rising time and falling time

Part Number: LMR33640

Hi expert,

Could you please measure the Rising time and Falling time of SW node?

Condition,

Vin=24V

Vout=5V

Iout=3.5A

Device : LMR33640DDDA  (1000kHz, SOIC)

I check it on webench as below,

It is 0.1nsec. I think, it is too faster, can I believe this simulation?

Thanks

Muk

  • Hi,

    Yes, it's too fast. You can apply for a free EVM sample of this device and test it. Thanks.

    Hi,

    OK, it's glad to help and we need to order some EVMs of this device, it might take some time maybe I can receive it on mid next week. Once I receive it, I will make the test and attach the results for you.

    Best Regards

    Hi,

    I just checked the status of this EVM board order, it's still on the way. It looks there is some delay, I will do the test once I receive it, thanks for your consideration.
