What is max current on LM27402 for 12Vin/9Vout ?
and Antminer S9 is using LM27402 for 12Vin/9Vout/30A, Are they using in the over-specs?

Hi,
LM27402 is a controller. The output current that it supports depends on the external fets,inductor rating and most importantly thermal considerations for the whole design.

Hi,
This is a standard number given to single phase controllers. With the advancement of FET technology and with the right design criteria it is able to push the boundary of 30A. Controllers can be seen as building block parts and its upto the designer to make design choices to support his current needs.
