Hi team,
Customer want to measure loop gain of TPS62142 which is fixed output.
But feedback resisters are integrated to the IC so we don't know how to measure.
Could you advice how we measure the loop gain.
I know this device is very stable due to DCS control as long as we follow your recommending LC filter.
It looks adding resister between Vout to Vos is good but the Vos is connected to 2 blocks, direct control & compensation and error amp, so I don't have confidence.
Best regards,
Koyo
