Thread Summary

                The user inquires about setting the inductor current for the MAX77675, which uses valley current control, unlike the MAX17271. The final answer clarifies that the inductor current cannot be directly configured but suggests using the spreadsheet to compute the current based on system voltage and load. Additionally, the power mode and status/interrupt bits can be configured and monitored to manage system overload conditions.

Product Number:   Max17271 and  Max77675  

    		        		        		        
Software Version: .

    		    		    

		    		    
		    			

			    
The Max17271 allows to select 4 different values (register map) of the Inductor Peak Current Limit (ilim), but the Max77675 has a different approach (Valley Current), why? and how Could I set (using the register map) a specific level of the inductor current for this part (Max77675) ?


Please, could you help me?


Regards!
