336-W auxless AC/DC power supply reference design with 80 PLUS platinum compatible performance

Overview

TopologyLLC Resonant Converter
Input voltage90-265 V
Output 124 V / 10 A
IC revisionB

Description

This reference design uses UCC28056 CRM/DCM PFC controller and UCC256304 enhanced LLC controller with integrated driver to provide 24-V/10-A output (continuous, 14-A peak) from universal AC input. This design achieves 92.8% peak efficiency at 115-Vac input and 94.9% peak efficiency at 230-Vac input. The efficiency and power factor numbers also meet both 115-V and 230-V internal 80 PLUS Platinum specifications and DoE level VI requirement.

Features

  • Low Input Current Distortion and Near Unity Power Factor Down to 10% Load◦Enables Compliance to IEC1000-3-2
  • Ultra-low No-load Input Power (25 mW at 115 Vac, 40 mW at 230 Vac)
  • Excellent Efficiency Over Range Of Load
  • Enables <60mW Standby Power at 115Vac and <80mW Standby Power at 230 Vac in PFC+LLC System
  • Enables Compliance To Green Power Standards Without Disabling PFC◦EuP Lot 6 Tier 2, CoC Ver. 5 Tier 2, Energy Star forcomputers Ver. 6.1, DOE Level VI
  • Ultra-low Audible Noise Output
  • Burst Mode With Soft-entry and Soft-exit Periods
  • Enhanced EA, Responds Rapidly to Load Steps Without Degrading Input Current Distortion
  • Valley Synchronized Turn-on Requires No Second Winding On The Boost Inductor
  • User Adjustable Valley Delay
  • Low Start-up Current Consumption (<46 µA)
  • Wide VCC Range 8.5 V to 34 V
  • Cycle-by-cycle Current Limit
  • Second Independent Output Voltage Protection
  • Integrated Over-temperature Protection

Typical applications

  • Gaming / Set Top Box / AC Adapter Front End
  • LED Drivers and Luminaries
  • Desktop Computing / Digital TV
  • Entry-Level Server and Web Server
