Part Number: UCC3804 Other Parts Discussed in Thread: UCC3813-4 , UCC3800 Hi
I see the specifications UCC3804 and UCC3813-4 are similar, but the price are different. What is the difference between these two?
thank you.

Are you asking if UCC1804 and UCC3804 have similar die?
Are you asking if we make a bare die version of the UCC1804 or UCC3804?
Thanks,
Daniel
