Tool/software:
Hi TI expert,
The internal compensation is designed in TPS25830, we'd like to know compensation performance. As the BUCK control involves current detection, could you please share the loop test method, such as test setup?
Thanks!
Michael.
Hi Michael,
We use a method called "AC Coupled, Transformer Method." AP instruments, who makes the test equipment, has good documentation on how this works. I'm struggling to find the exact pdf I usually refer to. I have done this test several times with other TI devices and the setup should be similar. The one thing I'm not sure about is the RSET resistor. I am not certain if opening or shorting this resistor will cause issues with internal circuitry.
Regards,
Eric
