LMZ31520: SENSE+ to Vout via extra resistor ?

Part Number: LMZ31520

Hi,

SENSE+ seems connected to ADJ pin via 1K43 internally.

For my application, the resistor between ADJ pin and VOUT must be >=6K

Can I add extra resistor (e.g. 4K7) in series from SENSE+ to Vout to achieve this without unexpected side issues ?

(I understand Table 1 is not valid anymore to calculate Rset)

thx,

Rudi

Hi Rudi, I'm checking with the module design team on their recommendation on this. As we have holidays in the US this week, please allow until next week for an update.

I received feedback from the design team. We do not expect issues with adding a resistor in series from SENSE+ to VOUT.
