So Isys+Iout (VR5510 LV regulator current consumption + VR5510 VPRE external load) should be no more than 10A.&nbsp;You can try 7A instead.&nbsp;</SPAN></P> <P><SPAN><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="1.png" style="width: 248px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/365172i51C2202E7AACE337/image-size/large?v=v2&amp;px=999" role="button" title="1.png" alt="1.png" /></span></SPAN></P> <P><SPAN>BRs, Tomas</SPAN></P> Wed, 12 Nov 2025 07:27:47 GMT https://community.nxp.com/t5/Other-NXP-Products/NXP-GUI-PMIC-VR5510-calculate-problem/m-p/2203339#M30587 TomasVaverka 2025-11-12T07:27:47Z
