Hi Yusuke,

What is the current level in each path ?

LM74700 does not support priority power-muxing as GATE cannot drive back-to-back FETs. Please use LM74800-Q1 as per figure-15 in https://www.ti.com/lit/an/slvaes2/slvaes2.pdf

Hi Rakesh,

Thank you for your kind response.
The "SLVAES2 material" made the customer interested in LM7480X.

However, the LM74800 is a preview product.
Could you tell me the details of the LM74800 development schedule and RTM schedule?

Best regards,
Yusuke

Hi Rakesh,

Thank you for your information.

I would like to introduce the LM74800.
However, LM74800 only sells sample versions.

Could you tell me your RTM schedule?
Is "V(A-C) linear regulation and comparator or V(A-C) comparator only" the only difference between 0 and 1?

Best regards,
Yusuke
