Description

This reference design is a 450W high-efficiency and super transient AC/DC converter for desktop PC PSUs, gaming PC PSUs, entry-level server PSUs, and other low-cost AC/DC PSUs. The circuit consists of a front-end continuous conduction mode (CCM) power factor correction (PFC) circuit, followed by an LLC-based second stage. The design uses the UCC28180 controller for the PFC stage and UCC256301 controller for the LLC stage to achieve a compact and robust control structure. Synchronous rectification based on the UCC24612 and low RDS(on) FETs aids in achieving higher efficiencies. This reference design can be used as an AC/DC supply in many applications demanding efficient and super transient power conversion.

Features
  • Peak efficiency 93% @ 230VAC for whole stage
  • Full power delivery across wide AC input range:  85 - 265VAC
  • Leading transient performance (half duty-cycle response for line transient and dynamic load)
  • Single layer PCB design to achieve low solution cost
  • Robust protection built in
