Although you are technically still married, it sounds like you are now separated so yes you can file for child support. And in fact, separation is the triggering event for just about all such issues, including but not limited to child custody, spousal support, division of property/debts, etc. You should consult with an attorney before doing any further to ascertain whether you may want to proceed on additional claims besides just child support. Please note that you cannot file for divorce itself until you have been separated for 1 full year.
