Brief: Stay tuned as we highlight the most important features and real-use results. In this video, we demonstrate how the UCC28056CDBVR PFC Controller operates across different modes, from transition mode at full load to DCM and burst mode for light loads. You'll see how it achieves ultra-low standby power and high efficiency, making it ideal for applications like desktop computing, LED drivers, and industrial power supplies.
Related Product Features:
  • Implements mixed mode operation with transition mode at full load and DCM at reduced load for optimized efficiency.
  • Burst mode operation enables ultra-low standby power below 80 mW at 230 VAC in PFC+LLC systems.
  • Valley switching with user-adjustable delay eliminates the need for a second boost inductor winding.
  • Wide VCC supply range from 8.5V to 34V supports versatile power supply designs.
  • Cycle-by-cycle current limit and independent output over-voltage protection enhance system safety.
  • Integrated over-temperature protection ensures reliable operation in demanding environments.
  • Complies with stringent energy standards including EuP Lot 6, Energy Star 6.1, and DoE Level VI.
  • Supports power stages up to 300 W with sinusoidal input current and near-unity power factor.
