LM61460EVM: Transient performance

Albert Sun

Part Number: LM61460EVM

Hi,

Do you have any transient (0.05A<->6A) test results based on LM61460EVM in PFM mode? i would like to know performance for 3.3V and 5V output.

hi, Albert,

we have a load transient waveform in datasheet, please check ,

Hi Elena,

Is it using EVM, same LC configuration for test? Could you please confirm? You know the transient performance without specific L-C will be meaningless.

hi, Albert,

Yes, usually the waveform on datasheet is from the EVM board.

HI Elena,

Do you have a more clear waveform for below 4 waveforms? The undershoot and overshoot spec is vague and I cannot tell the exact number. Thanks!

hi, Albert,

This is published on datasheet of LM61460Q, so that's is the final result we have. Vout is 200mV/DIV, the worse case should be 300mV around.
