Hi team

I have the following question on this IC:

- can we use the buck 1 to power buck 3-4-5, or, do we use external power for powering these bucks ?

- what happens if i use the feedback network in buck 2 and 6 ? 

BR

    Hi William,

    Buck 1 can be used to power Bucks 3-4-5 as long as the correct voltage and current requirements are still met.

    The feedback network for buck 2 (FBGND2 & FBVOUT2) and Buck 6 (FBVOUT6) are necessary for the proper operation of the bucks.

    Thanks,

    Daniel W
