NOTES:
10. D
12. F1, F2 are optional and can be eliminated depending on power system configuration and requirements.
13. DC/DC #1, 2 configuration is based on Vicor V48B48C250AN3.
11. Remote Sense pin (+S) on both DC/DC converters has to be connected either directly at the module output (Sa closed) or to the CB point (Sb
