TPS63810: power consumption when no load and FPWM mode

Hi  Given,

under FPWM mode, the consumption is not only depend on device itself, but also the inductor.

so, it is better you can do a bench test with the used inductor to confirm.

Hi Tao, 

Thanks for your reply. 

why does it has relationship with inductor? Thanks.

Hi   Given,

during FPWM mode, the inductor will have core loss and wire loss even with no load. they are big enough and you can not ignore them.

Hi Tao, 

Got it. I just want to know the Iq of our IC at this condition. Thanks.

Hi   Given,

Iq always got under PFM mode.

Hi Tao, 

Yes. So I use power consumption of our IC when in PFM mode with no load. Thanks.
