Features for the UCC28056

  • Ultra-low no-load input power enables < 80-mW standby power at 230 VAC in PFC+LLC system
  • Excellent light load efficiency and high efficiency over wide range of load due to multi-mode TM and DCM control
  • Enables low system cost through FET drain valley synchronized turn-on which eliminates need for second winding on the boost inductor
  • Enables compliance to green power standards without disabling PFC
    • EuP Lot 6 Tier 2, CoC Ver. 5 Tier 2, Energy Star Ver. 6.1, DoE LevelVI
  • Burst mode with soft-entry and soft-exit periods enables ultra-low audible noise output
  • Enhanced error amplifier, responds rapidly to load steps without degrading input current distortion
  • User adjustable valley delay ensures valley switching
  • Low start-up current consumption (<46 µA)
  • Wide VCC range 8.5 V to 34 V
  • Cycle-by-cycle current limit
  • Second independent output over-voltage protection
  • Integrated over-temperature protection
  • Create a custom design using the UCC28056 device with the WEBENCH® Power Designer

Description for the UCC28056

The UCC28056 device drives PFC boost stages based on an innovative mixed mode method thatoperates in transition mode (TM) at full load and transitions seamlessly into discontinuousconduction mode (DCM) at reduced load, automatically reducing switching frequency. This deviceincorporates burst mode operation to further improve light load performance, enabling systems tomeet challenging energy standards while eliminating the need to switch off the PFC. UCC28056 candrive a PFC power stage up to 300 W, ensuring sinusoidal line input current with low distortion,close to unity power factor. When used with the LLC controller UCC256403/4, and dualsynchronous rectifier controller UCC24624 lessthan 80 mW system standby power can be achieved, enabling PFC always on architecture andeliminating the need for an auxiliary converter. This with FET Drain valley turn-on with simpleboost inductor allows fewest component count and reduced system cost.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships  tube or tray  devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
