Hello.
I have a question. Please tell me.
Looking at the data sheet, Pin3 and Pin10 of LT3591 are described as NC.
However, looking at Figure 11, they are connected to the SW and CAP terminals, respectively.
Is there any problem if the 3pin and 10pin of the LT3591 are not connected to SW and CAP and are NC?
Can you tell me if NC is a typo in the datasheet?


Best Regards.
The datasheet is correct, or other way: It's very very unlikely to have such an obvious error with a part in the field since 15 years.
No need to connect pin 3 and 6. And no issue to have them bound to SW and CAP(datasheet, demoboard as well)
