LP87524-Q1: Phase margin measurement

Part Number: LP87524-Q1

Hi team,

Can I measure phase margin and draw a bode plot of LP8752x-Q1 by inserting series resistor in between OUT and FB_Bx pin?

Hello Tsuji-san,

Yes it is possible. You can check this document for basic connection diagram for the measurements we have done:

Make sure the injected signal amplitude is not too high, we have typically used 10...20mV signal level.

Thanks.
