First question asked Welcome!

Hi Team ,  

 We wanted Design with IR38164  below requirement 
Input 12V and Output - 5V   : 15A Typical  and Peak current 25A , Data sheet Mentions  Output can be set through resistor Divider  on Feedback pin or PMBUS.

Could please provide more details on Setting VOUT =5V  on Resistor Divider and also on compensation values. 

 

Thanks 

Uday
