Part Number: TIDA-01494

Hello!

TIDA-01494,this scheme is for 24V 20A output. I want to turn it into a 48V20A output.

I have doubled the number of secondary turns on the transformer. Besides, what other changes do I need to make？

你这个已经相当于要重新设计了，除了匝比，变压器感量，反馈等等都是要重新设计的。建议按照datasheet里面的案例重新计算设计。

Thank you for your reply.

The most important part is the feedback part, I don't know how to get started. Please give me some suggestions

I have now doubled the secondary side of the transformer. If I disconnect the feedback, I can output 48 V , but If feedback is connected, the output is still only 24 V . I know there was a problem with the feedback, but I won't make any changes. Could you please give me some suggestions ，Thanks

相关设计按照datasheet第48页之后的设计步骤确认一下就好。

我们也没有其他更多的资料，TI仅仅在datasheet里面有详细的设计步骤。
