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.
