Other Parts Discussed in Thread: LM74670-Q1, LM74720-Q1, LM74722-Q1, LM74721-Q1

Hi All,

I would like to know whether TI has similar product against the LT8672IDDBM.

This device combine a boost structure for internal power but I think TI do not have such device.

TI's closest device might be LM74670-Q1.

Could you kindly help to check whether you have better suggestion for this part?

Looking forward to your reply.

Thank you.
