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.
The Philips TEA1039 is a bipolar integrated circuit designed for the control of switched-mode power supplies (SMPS). It functions as a complete control system when paired with an external error amplifier and voltage regulator, capable of directly driving the SMPS power transistor in small systems. The circuit supports both frequency and duty factor regulation modes and is suitable for flyback and forward converters.
