Features & Applications

The TEA1750T/N1/DG,518 is a Third generation (GreenChip III) SMPS controller IC. It combines a controller for Power Factor Correction (PFC) and a flyback controller.

The high level of integration allows the design for cost-effective power supply with a very low number of external components.


  • Integrated PFC and flyback controller
  • Universal mains supply operation (70 V AC to 276 V AC)
  • High level of integration
  • On-chip start-up current source
  • Valley/zero voltage switching for minimum switching losses
  • Frequency limitation to reduce switching losses
  • Burst mode operation if a low load is detected at the flyback output
  • Valley switching for minimum switching losses
  • Frequency reduction with fixed minimum peak current
  • Safe restart mode for system fault conditions
  • Continuous mode protection by means of demagnetization detection for both converters 
  • UnderVoltage Protection (UVP) (foldback during overload)
  • Accurate OverVoltage Protection (OVP) for both converters 
  • Open control loop protection for both converters
  • IC OverTemperature Protection (OTP)
  • Low and adjustable OverCurrent Protection (OCP) trip level for both converters
  • Soft (re)start for both converters
  • Soft stop PFC to minimize audible noise
  • Mains UnderVoltage Protection (UVP)/ brownout protection
  • General purpose input for latched protection, e.g. to be used for system
  • Overtemperature protection


  • Battery chargers for cellular phones
  • Standby supply for TV and desktop PC
  • Power supply for White Goods applications
