Hi Sir

Does TPS40425 need to check loop gain?

Form EVB sheet we need injection signal to R8(EVB), how many signal voltage we need ipuut? is also 10mV?

Hi Bogey,

If you have loop test equipment, it will be good to measure bode plot.

The injected signal can be 10-50mV.

Sweep frequency is from 100Hz to 1MHz.

Thanks

Qian
