LMZM33606: PGOOD_PU

Hello team,

I have a quick question for LMZM33606.

When pull up for PGOOD is done externally can PGOOD_PU pin be left floating?

Best regards,

    Hi Sato-san,

    I would suggest testing on an EVM when you get the chance but from what I can tell, it should work.

    The 100kOhm pull up resistor was meant to remove one additional BOM component for customers during design. If PGOOD_PU is left floating, it is as though the 100kOhm resistor is also floating so the customer would need to supply their own external pull up resistor on the PGOOD pin to a DC voltage source. 

    Regards,
