Produktöversikt

The TEA1721DT/N1 is a Switched Mode Power Supply (SMPS) Controller IC for low power applications (up to 5W) and operates directly from the rectified universal mains input. The device includes a high voltage power switch (700V) and has been optimized for fly-back converter topologies to provide high-efficiency over the entire load range with ultra-low power consumption in the no-load condition. It provides a circuit for start-up directly from the rectified mains voltage without any external bleeder circuits. The converter operates as a regulated voltage source from no-load up to the maximum output current and operates as current source that delivers the maximum current over a broad output voltage range. Using the TEA1721, a low power converter can be built with the minimum number of external components. The controller regulates the output voltage with primary-side sensing which eliminates the need for an additional secondary feedback circuitry and simplifies the design.
  • Primary sensing for control of output voltage without optocoupler and secondary feedback circuitry
  • Minimizes audible noise in all operation modes
  • Jitter function for reduced EMI
  • Very low supply current in no-load condition with energy saver mode
  • Incorporates high voltage start-up circuit with zero current consumption under switching operation
  • Overvoltage protection on feedback control pin with auto-restart
  • Undervoltage lock-out protection on IC supply pin
  • Over temperature protection
  • Soft-start by reduced peak current for zero and low output voltage
  • Demagnetization protection for guaranteed discontinuous conduction mode operation
  • Open and short-circuit protection of the feedback control pin
  • Short-circuit protection of the charger output
  • 700V High voltage power switch for global mains operation
  • <22mW Enables no-load power consumption
