Ripple current at output capacitors
Sure the output ripple volts can not be too high in your application .Ripple current heats up the output caps due to their ESR .The life of electrolytic caps decreases with temperature .You know the ripple current ,so with the ESR of the caps you can get power dissipation and heating .If you have concerns about product life you can use better caps or place more in parallel to get temperatures down .
