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 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.
