Control circuit for switched-mode power supply
Product specification
TEA1039
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. 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.
• Adjustable minimum frequency or maximum duty factor limit.
• Adjustable overcurrent protection limit.
• Supply voltage out-of-range protection.
• Slow-start facility.
