TFP410: Power consumption of TFP410

? ?

Part Number: TFP410

Hi,

I am going to new add a baterry back-up circuit to TFP410 for unexpected power lost. It is necessary to know the power consumption of the chip. Found in data sheet, Iidd is max. 250mA.

Can I use this Iidd to estimate the total power request of TFP410?

Hi,

The max 250mA current is measured with the test condition of Black and white checkerboard pattern, each checker is one pixel wide.

Looking at this e2e thread, https://e2e.ti.com/support/interface-group/interface/f/interface-forum/874109/tfp410-what-is-the-power-consumption-per-power-pin-section?tisearch=e2e-sitesearch&keymatch=tfp410%252525252525252520power#, the number is slightly higher than 250mA because the different test condition.

I would not budget the power at exact 250mA, but more than 250mA for additional margin.

Thanks

David
