Intel's 13th Gen Raptor Lake Desktop CPUs might be a refresh of Alder Lake but they won't be just a standard clock bump like previous generations. The Raptor Lake CPU lineup is expected to come with a range of improvements, one of them being DLVR.

The information regarding Intel's Raptor Lake CPUs utilizing the new DLVR 'Digital Linear Voltage Regulator' technology comes from Reddit through a patent which was first discovered by insider, UnderFox. Underfox has been covering patents of various companies and disclosing useful data that gets us an insight on upcoming technologies. The DLVR was also seen mentioned within the leaked slides discovered by Videocardz a while back. Like Haswell's FIVR, the DLVR will be utilized on Raptor Lake CPUs as an on-chip voltage regulator.
