ADP2360 as dc-dc converter for loop-powered system

Hi 

I'm designing a board which will be powered from loop-powered system with  24v/3.2mA input.

I want to convert it to 3.3V/12mA output.

So i want to use adp2360 as dc-dc converter but the problem is in LTSpice the minimum input current from supply is 50mA , which can be maximized with Rith.

I want to know if these type of dc-dc converter can be use for loop-powered application , and if not , is there any suggestion?

Thanks

Best Regard

  • hi, i also have this problem. i tested the circuit and saw the problem, the loop power systems must have the maximum current of 3.2 ma in 24v system but in this ic , the input current on 24v in best situation is 50ma peaks and i think there must be some problem in adp2360 input circuit.(because of iswitch).i have also this same question.best regards
