Our customer is looking for a DC/DC Converter:
8KW
700V input
24V output @ 333A
Need automotive grade parts
Need functional safety
Cost Goal < $500

This is the only reference design I found that looks close - https://www.infineon.com/cms/en/product/evaluation-boards/ref-dab11kizsicsys/ (REF-DAB11KIZSICSYS 11 kW SiC bi-directional DC/DC converter board for EV Charging and ESS applications), but it is not a great fit. Input voltage and power level look good but output voltage way to high - Primary side bus voltage Vbus - 750 V, Secondary side bus voltage VHV - 550-~800 V.

Do we have a better solution to recommend?

Hello @CDarrow ,

Infineon portfolio currently doesn't hold any reference design which is close to the specifications requested. The available reference designs will have to be scaled for the customer specifications for which we can offer support. 

Also, we have explicit application pages for almost all modules of the Electric drive train, which can be of great use for the customer.

Below page contains the topology and the respective component recommendations for HV-LV DC DC converters used in automotive application.

Kindly let us know if any further inputs are needed on this topic.

Regards
