TPS7A45: Startup measurement request

Kazuhiko Hirano

Part Number: TPS7A45

Hello,

My customer looked at the following E2E thread, and they would also like to know the rise time at no load and Iout=1.5A respectively.
https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/717424/tps7a45-start-up-time

Their schematics is as follows. Could you modify the EVM and take waveforms like the E2E thread, please?

Best regards,

Erin,

How are you doing?
I attached wrong schematics before.
I attach the correct schematics here again.
Could you modify the EVM and take waveforms like the E2E thread for no load and Iout=1.5A, please?

Best regards,

Hi Kazuhiko,

Thanks for your patience. Here are the measurements at full load and no load. I used the TPS7A4501 EVM per the schematic you shared for both measurements.
