TEA1039 Datasheet

The TEA1039 is a bipolar integrated circuit intended for the control of a switched-mode power supply. Together with an external error amplifier and a voltage regulator (e.g. a regulator diode) it forms a complete control system. The circuit is capable of directly driving the SMPS power transistor in small SMPS systems.

TEA1039 features

  • Suited for frequency and duty factor regulation.
  • Suited for flyback converters and forward converters.
  • Wide frequency range.
  • Adjustable input sensitivity.
  • Adjustable minimum frequency or maximum duty factor limit.
  • Adjustable overcurrent protection limit.
  • Supply voltage out-of-range protection.
  • Slow-start facility.
