Part Number: LM5180-Q1

Hi team,

Could you please advise the tr and tf (rising, falling time) of low side FET?

I need this information to cacluate the power consumption.

Hello Shinji,

As these parameters are not available in datasheet, I need to ask these data from design team, will get back to you soon.

Thanks,

Hareesh.

Hello Shinji-san,

Thanks for your patience!

I am following up with design team, but it is taking some time. I will update you once I receive the data.

Regarding power consumption, since everything is internal, why customer require to calculate switch losses / power consumption?

If customer need device power loss, they can find in efficiency graph from design calculator excel: LM5180DESIGN-CALC Calculation tool | TI.com

Also, quiescent / supply current data is given in datasheet, customer can use this if needed. Please find below snapshot,

I will update you once I receive the tr, tf data.

Thanks,

Hareesh.
