Hi,

What is the role of R3? Is it to facilitate the loop response of the test circuit? Thanks.

Charlie,

We recommend placing a resistor (either 0Ohms or 10Ohms) on the feedback path between the output and the sensing pin. This way, if there is ever an issue that needs to be debugged on the output, we can disconnect the sense line.

Thanks,

Kadeem

Hello Charlie,

The 10 Ohms resistor R3 serves to measure the Gain/Phase loop as well. Please close this thread as resolved and let me know for further support.
