VOSNS+ at load or OUTPUT?

Thread Summary

The user inquired about the connection of the VOSNS+ pin on the LTM4670, specifically whether it should be connected directly to the output pin or at the load point after downstream capacitors. The final answer from technical support recommends connecting VOSNS1 to the OUTPUT pins before the 100uF bulk output capacitors, as demonstrated on the DC2891A demo board.

Hello,

should the VOSNS+ pin be connected directly to the output pin of the LTM4670, or is it acceptable (and advisable) to connect it at the load point, i.e. after the downstream bulk and filter capacitors? I am particularly interested in understanding whether the additional phase lag introduced by these capacitors could impact loop stability or lead to undesirable dynamic behavior.

Thank you very much.

Best regards,
Rostilj
