Hi community,
Our partner have some question about MMPF0100 connection when unused.
Please see Table 1 of AN4717 (Schematic Guidelines for the MMPF0100).
[Q1]
The recommended connection when not used for the following pins are "Leave floating".
VGENx
VINREFDDR
VREFDDR
SWxFB
SWxLX
We want to confirm the meaning of "Leave floating".
I understand "Leave floating" means "No Connect", so all circuits and materials written in "Recommended connection" column (e.g. capacitor, shottky diode for SWBSATLS) are NOT required.
Is this correct?
[Q2]
Please see the "Recommended connection when not used" for VINx.
These are written as "Connect to regulator with output voltage < 3.*V", or "Connect to VIN".
I understood these power supplies are required even if all VGEN outputs are unused, we cannot be these pins as "Leave floating".
Is this correct?
Best Regards,
