Hello Arjun,
The TEA2017DB1580, based on the TEA2017 LLC and PFC combo controller, is indeed primarily designed for a 12V/20A output as set by its external components and design configuration. To change the output to 24V/10A or 48V/5A, you would need to make substantial modifications to the feedback loop, transformer winding ratio and possibly the power stage components to support these new voltage and current specifications. Given the complexity of these changes and considering thorough testing that would be essential to ensure stability, efficiency etc. we do not really recommend it.
BRs, Tomas
