TEA1039 - switched-mode power-supply

General Description

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.

Key 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. QUICK.

INTEGRATED CIRCUITS DATA SHEET TEA1039 Control circuit for switched-mode power supply Product specification File under Integrated Circuits, IC02 August 1982 Philips Semiconductors Product specification Control circuit for switched-mode power supply GENERAL DESCRIPTION TEA1039 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. It has the following features: • Suited for frequency and duty factor regulation. • Suited for flyback converters and forward converters. • Wide frequency range. • Adjustable input sensitivity.
