TPS5405 efficiency at 24V

M. B.

Prodigy 155 points

What is the power conversion efficiency of this chip at 24V (eg. at 1 Amp) ? The datasheet only lists efficiency at 12V (around 90% @ 1A). I need to know that there will not be too much heat to dissipate.

Hi M. B.

I will check if this data is available somewhere or find someone to help with this request then update if I find anything. The quickest option may be to order an EVM and test.

Best Regards,
Anthony

Hello Anthony,

i am also planning to use TPS5404 with 24V input.

This data could be helpful to me as well.

Meanwhile i am also trying to get EVM.

but it will still be few days before i actually get it.
