TPS7B81-Q1: Inrush Current

Manabu Ishida

Part Number: TPS7B81-Q1

Please confirm what will be the waveform plot or peak current value of inrush current at VIN=EN=12 V, Cout=10uF, Vout=5 V?

I checked the datasheet, but I couldn't find it.

best regards,

Hey Manabu,

I will check our validation data, but this may need to be a lab measurement.

Hi Juliette-san

I used PSpice for TI to check the inrush current at startup of TPS7B81-Q1.

The inrush current in the simulation appears to be over 10 A.

So,please share the result of measuring inrush current data in lab.

best regards,

Hey Manabu,

I will forward this to one of our application engineers that can take the lab measurement.

Best,

Juliette

Hi Manabu,

There is an EVM available for purchase for this device: https://www.ti.com/tool/TPS7B81EVM-025

Please purchase an EVM so you can make the inrush current measurement.

Regards,

Nick
