I am working on DC to DC converter with specification :
Input range 40VDC to 70VDC and output 13.5VDC/10A
Is there any application note from TI to match this requirement , I can also use Transformer at input or output for Isolation, but application note should be low cost.
I try switching regulator(LM5085-Q1) with specified input voltage range but cost getting too much high.
