one possible solution is an SMPS and tda7294.
i em not sure what high current dc-dc boost converters are available, but surely others can share a few.

without a boost converter tda1562q could be mentioned, but it is a discounted item.
it is class H , so the output power is kindof.. "depends on how you look at it".

if possible, i would go for the boost converter methood.
