OR:  

The TEA1716 integrates a Power Factor Corrector (PFC) controller and a controller for a Half-Bridge resonant Converter (HBC) in a multi-chip IC. It provides the drive function for the discrete MOSFET in an up-converter and for the two discrete power MOSFETs in a resonant half-bridge configuration.The integrated burst mode and power management functionality of TEA1716 enable resonant applications that meet the Energy Using Product Directive (EuP) lot 6 (< 0.5 W in standby mode). Highly efficient and reliable power supplies providing from 90 W to 500 W can be designed easily using the TEA1716, with a minimum of external components.

Features and benefits

  • Integrated PFC and HBC controllers
  • Compliant with Energy Using Product Directive (EuP) lot 6
  • Adaptive non-overlap time
  • Capacitive mode protection for HBC controller
  • On-chip high-voltage start-up source
  • Stand-alone operation or IC supplied from external DC source
  • Boundary mode operation with on-time control
  • Universal mains supply operation (70 V to 276 V (AC))
  • Valley/zero voltage switching for minimum switching losses
  • Frequency limiting to reduce switching losses
  • Burst mode switching with soft start and soft stop
  • Integrated high-voltage level shifter
  • Adjustable minimum and maximum frequency
  • Safe restart mode for system fault conditions
  • Overtemperature protection
  • Undervoltage protection for mains (brownout), boost, IC supply
  • Overcurrent regulation and protection for both controllers
  • Accurate overvoltage protection for boost voltage
  • Integrated burst mode sensing

Applications

  • Notebook adapter
  • Desktop and all-in-one PCs
  • LCD television
  • Plasma television
