PCB with LS1012A processor

I am designing a PCB with LS1012A processor from NXP which has PMIC and DC-DC regulator. DC-DC regulator (MC34713EP) went end of life. Can I find an alternative IC that will achieve the same requirements?

At first please tell us why did you choose MC34713EP? To supply 3.3 V to the processor ?

I chose it because it was listed as part of the requirement for that assignment that am undertaking.
