Hi,

Does LM61495 feedback pin can support voltage switch via chagne feedback resistor change?

We want add a parallel resistor and MOSFET to change to the Rfbb is okay?

Thanks!

Hi Jeff

Yes, the LM61495 output voltage can be changed by modifying the feedback resistor divider. Adding a parallel resistor to RFBb and switching it with a MOSFET is acceptable.

Ensure the resulting FB voltage stays within the specified regulation range and that the MOSFET leakage and added capacitance are minimal to avoid stability or transient issues during switching.

Thanks and Regards
