As we want to use TPS40322 as single-output with one-phase. How to deal with the signals of unused channel(BOOT2, CS2, EN2/SS2/GSNS/FB2, HDRV2, ILIM2, LDRV2, PG2, PGND2, SW2)? Just let them unconnected? Or did we need pull-up/down to GND/VCC?
And by the way, in our system, the maximum output current is about 18A, so could one-phase output support this?
Thank you!
