Hi

 

when I use NXP GUI to do some calculation for VR5510.

Why this Iout value of VPRE could not bigger than 7A?How can I increase the upper limit of the current?

Hello Michael,

VR5510 VPRE current capability is 10A. So Isys+Iout (VR5510 LV regulator current consumption + VR5510 VPRE external load) should be no more than 10A. You can try 7A instead.
