What I need is a DC-DC converter for 17A for only the first 1 minute, then =
the system will need only 5A

Vdc input 24 V from 2 batt (truck) VDC output 24V. I know that is dificult =
to make a DC DC with the same input and output, I think that I can use a Bo=
ost-buck configuration for this.

Any suggestions?
