Hello,

I would like to know what is Quiescent Current of this IC, as it is not stated in the datasheet.

Operation conditions are: Vin=36-60V; Ioutput=0.7A;Fswitching=175kHz

Timur, this may require us getting the EVM to take this data for the application specific configuration.

Please give us some time to acquire the EVM if necessary.

Hello Marshall,

Thank you. Will wait for your response.

Sorry, I just got back from a US holiday.

I forgot to mention that efficiency can be measured via webench with your specific input and output power configuration.

This data is correlated with validation data.

Does this help?

Hello Marshall,

I was asking about the quiescent current of this IC, not efficiency

I saw you specifiy the output current, so I thought you mistyped.

Iq is highly dependent on BOM, with the inductor and input voltage being big influencers.

Do you have an inductor in mind for your application.

Additionally, if you do want to have an additional device to evaluation.

LMR36006 would be a device that could fit your application. It has a PFM mode for good no load iq.

Hello Marshall,

We need AEC qualified components.
That is the diode we used: V2PM10HM3/H

Hello Marshall,

What about the quiescent current of LM5010A-Q1?

I will have a look at the part you suggested

Sorry for delayed response

Do you still require data for LM5010A?

Hello Marshall,

Yes please

Hi Timur, you can assume the minimum of the maximum duty cycle to be 70%.

Unfortunately, we can not guarantee this specification by datasheet.

This specification in the datasheet I believe answers your question?
