Abstract
This work presents a direct 48–1-V DC–DC point-
of-load (POL) converter for efficient high-voltage conversion.
Conventional hybrid topologies face limitations of large number
of off-chip components and limited operation ranges. By com-
bining the three-level buck converter with the hybrid Dick-
son converter, the proposed topology shows ten times reduced
switching voltages with only five off-chip flying capacitors—a
near 50% reduction compared with prior works. The reduced
voltage stress enables us
